Audacity VS OREMO – Which is Best For Recording UTAU?

Recently, Kiko went over installing the UTAU software, but that leaves us with a question; how do we even record for the UTAU software? Not to worry! We’ve drawn up a small introduction to free audio recording programs for the UTAU software. These two different applications are commonly used with UTAU for recording voicebanks. We will be covering two names that you may be familiar with: the UTAU community’s good friends, Audacity and OREMO.


Well, to put it simply, Audacity gives you the audacity to record. Okay, okay, I’m sorry, I couldn’t help myself. 

Ahem. Anywho. Audacity is a free, open-source, cross-platform audio software. It’s a relatively simple program, but it is a great starting point if you are overwhelmed with voicebank recording. With Audacity being so bare-bones, you can use it to learn the basics of recording any audio in general. You can cut, copy, splice, or mix sounds together as well as apply numerous sound effects like pitching a sample up/down. 

However, it isn’t the best for voicebanks due to the time and file sizes created when recording. When recording a voicebank, users in Audacity will either need to record one sample at a time, exporting and naming the file afterward, OR they must record in one long track, splicing and naming each recording separately afterward. That’s a lot of extra work! So, why do we still recommend it?


Audacity is fantastic for post-processing. The software features multi-export, which is a very handy tool. After your recordings are complete, you can drag and drop several audio samples into the software if need be. Many users take this approach when removing background noise from their recordings. Afterward, one may use Audacity’s ability to multi-export each individual track separately, and Audacity will use the track’s name to name the exported samples automatically.


Alternatively (and much more fun) is Audacity’s impressive batch-processing capabilities. With batch-processing, a user can create a unique macro (once referred to as a “chain”) of events that Audacity will apply to any audio files within a designated folder. For instance, STUDIO OGIEN uses chains for KASAI OG01 and APOLLO OG0X’s development, as both use Audacity’s pitch effects to procure their unique voices. These chains include information on how high or low to change the pitch of each sample, as well as what file type to export as (.WAV). Their audio files are run through the chains and automatically exported for minimal work on the team’s part, rather than adjusting the pitch on each individual sample.

Audacity’s Macro option, under the Tools dropdown

To create a macro

  • Go to Tools
  • Select Macros…
  • Click “New”
  • Insert a name for the macro
  • Choose and inserts effects
  • For UTAU recordings, make sure to include “Export as WAV”
  • Save it!

A macro has been created! The user can now apply the macro to their preferred audio samples. Note, in the team’s experience, macros do not work well with the Noise Removal tool. 

To use the macro

  • Go to Tools
  • Select Macros…
  • Select the macro
  • Browse to the file folder and select the desired files
  • Select Open
  • The processed files will be placed in a new folder within the folder of the original files

OREMO, developed by nwp8861, is the main audio recording software that STUDIO OGIEN uses in-house. Why? OREMO is explicitly designed to work with UTAU’s voicebank recording methods. The learning curve is upped a bit when you begin OREMO, but many in the community recommend starting with OREMO to help save time and sanity. 

One of the best things that OREMO has in its software is auto-saving, which automatically splits each sample into its own, named .WAV file. No more manually exporting or naming files!

The OREMO User Interface

OREMO’s UTAU Specific Features

OREMO also supplies an array of features that improves the overall recording experience. Users can take advantage of the application’s BGM (which plays beats at a specific note while the user records, helping them keep on-time and on-pitch). This is a life-saver when it comes time to configure the OTO. Several community-made BGMs are available for download as well to fit the tastes of the user. The program also gives access to a built-in metronome.

OREMO also supplies a pitch guide, which, once a recording has been completed, will compare the pitch of the sample to a predetermined note (this is the red line pictured above). This helps the user to determine if their sample is on-tune. Users may also insert their favorite reclists into the program as well as a list of unique Suffixes. Essentially, one can record a multi-pitch voicebank with ease this way, as the user can simply select a Suffix to attach to the voice sample, and OREMO will automatically add the suffix to the filename.

Audacity doesn’t necessarily include the features above, making it a more difficult software to record with. As OREMO is much more specialized, one can save an abundance of time by utilizing this unique tool.


We understand that OREMO seems like the best option for recording a new voicebank. Still, sometimes, users prefer options they are familiar with rather than the community accepted software, which is OREMO. 

  • If you are looking just to practice audio recording and learning what all the terminology means, we say try out Audacity.
  • If you plan to record voicebanks (VC, CV, VCCV, or others), we recommend sticking with OREMO. 
  • For post-processing, we recommend Audacity or software similar to it.

Sneak Peek of STUDIO OGIEN’s 2022


Is it already nearing the end of our brief hiatus? The time has flown by, but as a team, STUDIO OGIEN has made valiant strides of progress through it. It’s now time for us to shine some light on our progress with a sneak peek!

This brief blog post is just to let you beautiful humans know what you can expect from us in 2022~!

So, What’s New?

Over the break, we created a calendar of all our future plans, and let me personally tell you, it’s a lot! We have recording sessions, blog posts, voicebank releases, and even more on the roster for this year. Now, what those releases are for and who is being recorded, I’ll leave that up to a surprise.

Social Impacts

We’ve maintained a steady flow of updates to all of our social media accounts over the break, which we strive to continue in the new year. During the hiatus, we were even able to get the Community tab on our YouTube which was a huge goal of ours!

Oh, All Right. I’ll Give You an Actual Sneak Peek

A minimum of four, yes FOUR(4), new voicebanks will be available by the end of 2022! We have really been striving to give you all more of our beautiful girls and I think we finally have been able to do it!

Download and Install UTAU

Hi everyone! 

Today, I will be going over the process of how to download and install the UTAU software onto your computer. This will be a learning experience for all of us! I have no idea what I’m doing, but Ceren is here to help me along the way, and I can help teach you all how to properly install the software without a hitch! (Well, there may be a hitch, but I won’t tell you about that…)

Changing Your System Locale

So, we need to do this thing in order to properly run the UTAU software. Before you try to skip this step, your UTAU software will read in gibberish when opened without doing this step. I know, we just wanna get to the fun stuff, but we have to do this for the ship to have smooth sailing. 

What does changing your system locale mean? All it means is that we are changing the locale for non-Unicode programs (I don’t know man, I’m just a writer. After some googling it appears that it’s just a term for readable character data.) from English to Japanese. 

If your PC doesn’t have Japanese already installed, head over to your Settings, select Language, then Add a Language. From this point, type Japanese into the pop-up box, select it, and hit the Next button. Next, deselect the “Set as my Windows display language” unless you wanna roll like that. You do you boo! But, if you want to keep your display language English, deselect that option. Last but not least, click that Install button!

Let’s actually change your system locale (for Windows)!

  1. Open the Control Panel
  2. Select the “Clock, Language, and Region” option
  3. Select “Region and Language”
  4. A window should pop up. Select the tab that is labeled “Administrative”
  5. Select “Change System Locale”
  6. A dropdown list will appear. Scroll until you find Japanese, then select it. 

BOOM SHAKA LAKA! UTAU should now be able to read UST’s correctly!

Have concerns? No worries, I did too. Changing the System Locale will affect how your backslash (\) is displayed, causing it to look like a yen symbol in some programs. I mean, it’s not like I use that in my writing or anything…..But,  I digress; let’s move on. 

Time to Download the UTAU Program

Now that our system can now register Japanese, let’s download the software! I don’t know about you guys, but I don’t understand much Japanese. Throw some French at me, then maybe. Anyways, we need to head over to this lovely website:, which will lead you directly to download the software.

When you get to the website, there will be some links followed by Japanese text. All you need to do is click the link that says v0.(latest version number) zipアーカイブ. This will launch a zip file, which you can unzip in your desired location on your computer.

This will open the fully operational version of the UTAU software. However, it will be entirely in Japanese. As I said earlier, I can no read that. How can this be fixed? There is an English patch available for us Western fans to utilize, which can be found here:

We need to create a new folder within the UTAU(version number) folder you have with this patch. Create a new folder and name it “res.” Once this is done, unzip the English patch file into this new “res” folder. 

We Made It!

That’s…that’s it. We did it! We all now have a fully functional version of English UTAU to create new UTAUloids and make songs! 

As a note of caution: if you try to pull the UTAU icon out of the folder and launch it, it will run in the default Japanese language. To stop this from happening, you need to keep the icon with the English patch in the folder. If you want to launch via the program icon, you can drag the icon to the taskbar/dock of Windows or go into the UTAU folder and click the icon there. 

Thanks for joining this adventure with me! I’ll be back soon with more learning about the UTAU program. So we can navigate this exciting new world together. 

Until next time!

OGIENOID Minecraft Skins

Let’s have some fun with OGIENOID Minecraft Skins!

Everyone enjoys games, right? The team at STUDIO OGIEN sure does! As a result of our love for games, we have been at work to create OGIENOID Minecraft skins of all the OGIENOIDs and we are happy to announce that they are ready to be shared with you all! You can head to each girl’s page to find them under “Downloads.” Also, you can download them here on this post for DIONE OG05 and VIRTUS OG02, who are currently unreleased! Below, you will see a showcase of all the skins and how they look when walking with them in-game.

Taking a look at the skins in Minecraft!


The original OGIENOID, KASAI, uses the 3px arm option for her skin.


Likewise, VIRTUS’s skin uses the 3px arm option.


Additionally, the lilac OGIENOID, THEIA, also uses the 3px arm option.


After that, our orange girl, HONOS, uses the 3px arm option as well.


Meanwhile, DIONE’s skin uses the 4px arm option. Since she is our main plus-sized girl, we feel this option represents her best.


Our mint momma, AXIS, uses the slim (3px arm) option.


Similarly, ATLAS OG07’s skin uses the 3px arm option.


Next, APOLLO OG0X’s skin also uses the 3px arm option.

YA-01 Artemis

Next, Artemis’s skin also uses the 3px arm option.

YA-02 Gaia

In addition, Gaia’s skin uses the 3px arm option.

YA-03 Lyra

Lastly, Lyra’s skin also uses the 3px arm option.

In conclusion, we hope you will enjoy creating and exploring while dressed as the OGIENOIDs in your Minecraft world!



Today, we meet STUDIO OGIEN. What is it? Studio Ogien (stylized as STUDIO OGIEN), was created in 2015 by Ceren (LadyOgien). The studio, at that time, was developed as a way for her to combine all of her stories and characters under one brand. However, as her friends began to offer their support for her UTAU characters, the studio began to grow into a multimedia project. Our team had this passion and drive to create a group that represents women of all walks of life. Together, the group has created the OGIENOIDs, a cast of digital idols created using the free shareware, UTAU. Studio Ogien has been actively creating vocal synthesis divas since its founding, with plans to expand into storytelling in the near future.

Where does the name STUDIO OGIEN come from?
Studio – a place where artists, painters, sculptors, photographers, and other expressive professionals create their works.
Ogien /ɔɡjɛɲ/ – directly translates as fire from the Polish language.

We like to interpret this as “We are a studio filled with a fiery passion.”

Current Vocal Synthesis Roster:

KASAI OG01, VIRTUS OG02 [unreleased], THEIA OG03, HONOS OG04, DIONE OG05 [unreleased], AXIS OG06, ATLAS OG07, APOLLO OG0X

There are a ton of people who are working on this project and we wanted to give them all a proper introduction!

Meet Our Team:


Founder, Director

Nice to meet you! My name is Ceren, and I am the Founder and Director of STUDIO OGIEN. I do a little bit of everything around the studio, assisting wherever I can. In other words, if STUDIO OGIEN published it, I probably helped with it, haha. 

I am a bit of a lurker. For a long time, I really didn’t want much attention on myself. Similarly, I didn’t want the studio to be noticed. It took a long time for me to be comfortable putting things out into the world. However, my friends at the studio have been my main driving force to continue the OGIENOID project, and their passion for the girls truly makes me want to work harder every day. Above all, I am grateful for all that they do, and I love my team so very much!

Let’s continue to create a brighter future every day through our efforts!

What Is UTAU? A Brief Overview

UTAU is a Japanese singing synthesizer application created by Ameya/Ayame. This program is similar to Vocaloid, a professional vocal synthesis software that would inspire UTAU’s creation. Furthermore, UTAU is an independent application that is free for anyone to download and use (there is also a shareware version with special features available, but the free version on its own is already perfectly solid). The program uses .wav files the user provides to create a singing voice, which will synthesize by introducing song lyrics and melody.

UTAU, like Vocaloid, presents the user with a piano roll. Additionally, users can input notes/midis/etc. into the software, add lyrics, and tune the vocal to create a semi-realistic singer, more commonly referred to as a voicebank. Moreover, each Voicebank is unique, with its own strengths, weaknesses, voice type, range, and terms of use.​

A look at the UTAU GUI​ ​ 

UTAUloids Rise To Fame

UTAUloids have been on the rise since the shareware’s release in 2008. Certainly, the most notable faces of the program are Defoko and Kasane Teto. Defoko being the built-in voice for the UTAU shareware, while Teto is the ‘face’ of UTAU. They both have immense popularity. A small fun fact: new Vocaloid fans often mistake Teto as an official Vocaloid voicebank! Check out their voicebanks in action below.

How Does It Work?

First off, we’re glad that you’re excited to jump into creating your first Voicebank, but there are a few things you need to know first!

Programs to Create Voicebanks

Fl Studio: A DAW (Digital Audio Workstation) used within the UTAU and Vocaloid communities for many years. It’s most used by these communities to mix songs/covers.

Audacity: A free-to-use DAW. It is typically used to record and splice voicebank samples.

Reaper: A popular DAW that offers a free trial period. Often used to mix songs and is rather user-friendly.

OREMO: A free-to-use program created specifically for recording Voicebanks. This program is a fan favorite for recording since it will automatically name a user’s voice samples as well as add aliases to the file name. Features a metronome and BGM function to keep recordings on time and on the tune.

setParam: Another program created specifically for use with UTAU, specifically OTO configuration. While UTAU possesses an interface for configuring OTOs, setParam offers a more intuitive interface and allows the user a much more detailed look at their recordings.

MIDI: (Musical Instrument Digital Interface) Often used in music production, it is a standard file format for communicating information between musical instruments. MIDIs can be used in the creation of UST files.

Resampler: A vital component of UTAU. This engine reads a Voicebank’s WAV files when the user plays a track in UTAU or when they render it for external use.

FRQ: Files generated by the resampler to properly read the Voicebank’s WAV samples. If you download a Voicebank that has FRQ files in it, don’t delete them! The creator may have edited them manually to fix errors and glitches in the Voicebank.

Voicebank Types:

CV: “Consonant Vowel” recording format. The smallest and simplest style of Voicebank, this is a great choice for beginners to get acquainted with the recording process.

VCV: “Vowel Consonant Vowel”, blends together the ending vowel of a sample with the consonant-vowel pair of the next. While it is more labor intensive to create compared to a CV bank, it’s the most popular form of Voicebank for its smooth end result.

Lite VCV: A simplified/compact version of a VCV Voicebank with more smoothness than CV. A good option for those wanting to branch into VCV.

CVVC: A CV Voicebank with “VC” samples to improve clarity and smoothness. Easier to record than VCV, but trickier to properly configure. This recording style can offer more flexibility than VCV, depending on the Voicebank.

Voicebank Styles:

VCCV: Developed by Cz, one may refer to this as the new standard for English UTAU Voicebanks. Widely supported by the community and praised for its clarity, though it does create an Americanized accent in a lot of Voicebanks.

Rentan: A recording style specific to CV Voicebanks. Samples are recorded all at once, rather than one at a time, within the same file. After being configured in UTAU, it works just the same as a standard CV voicebank.

Multipitch: A style of Voicebank that uses multiple single voicebanks, all recorded at different pitches, into one larger Voicebank. Allows for a much greater vocal range with a more natural sound.

Kire/Powerscale: A Voicebank type where, as the voice reaches higher pitches, the recordings become more powerful. Popular in the community and useful for Rock songs.

Appends: A term originally derived from Vocaloid (specifically, Crypton Future Media Vocaloids). These Voicebanks are recorded to fit a specific theme or timbre. Examples might be “Soft”, “Whisper”, “Power”, “Dark”, etc. Commonly recorded as stand-alone Voicebanks, but may also be included in Multipitch/Multi Expression voices.

Terms To Know For Post Production

Mora: The number of syllables in a voice sample. For example, “a-a-i-a-u-e-a” is a 7-mora style recording.

Prefix map: An important file for Multipitch Voicebanks, this is how UTAU knows what voice samples to play on which notes.

Tuning: In which the user warps, bends, and/or changes the pitch of a voice track in a Vocal Synthesis software. This is done to change the way the voice sings a song in order to make it more unique or more human-like.

Consonant Velocity: A configuration in UTAU that can be changed per track or single note. This affects how quickly the consonant part of the voice sample plays. Usually, this is used to avoid a “slurring” sound in playback for quicker songs.

Flags: Codes used by the Resampler to alter the voice properties of the UTAU. They can be used to add breathiness to a voice, reduce nasal tones, make the voice sound more masculine/feminine, and much, much more. The Flags are typically defined per Resampler, so some may offer different effects than others.

Alias: A name given to voice samples in the OTO. This tool can be used to assign multiple names to the same recording, which is commonly used in VCV banks.

Mixing: The process of taking vocal tracks and combining them with an instrumental in a pleasing way.

File Types

.WAV: The file format UTAU voice samples are recorded in. WAV is the only file type UTAU will use for a Voicebank on Windows computers.

.UST: UTAU Sequence Text Files. Similar to sheet music or a MIDI file (which can be turned into a UST), this is the main file type used in UTAU to store information about a voice track.

OTO: Also known as an oto.ini, this is the file used to tell UTAU how to distinguish between the starting point of a sample, where the consonant begins, where the vowel is, the cut off of the sample, and how much of the sample is okay to stretch on longer notes.

Additional Terms to Know When Working With UTAU Software

UTAU: The name of the software, it is also the Japanese word for “Sing”.

Vocaloid: Perhaps the most well-known Vocal Synthesis program, developed originally for use by professionals. It is a commercial program that requires the user to purchase the base software as well as each additional voice they may want to use.

UTAUloid: An older community term used to refer to a specific UTAU character. Additionally, this term originates from “Vocaloid” and is in use alongside it.

Pitch: How high or low a tone is.

Timbre: The character or quality of a voice, different from pitch or intensity. Youthful, gruff, feminine, etc. could all be descriptors of timbre.

Vocal synthesis: The artificial production of human singing voices/voice-like instruments, much like speech synthesis. Common term when referring to UTAU, Vocaloid, and other similar applications. 

Voicebank:  A collection of voice samples and OTO(s) compiled for use within UTAU as a functioning singing voice. A Voicebank is usually alongside a character or mascot that represents the voice. Often referred to shortly as a “Bank”. 

Vipperloid(s): A popular series of Japanese UTAU. You may recognize members such as Yokune Ruko and Sukone Tei. They originated from vip@2ch.

Nico Nico Douga/ニコニコ動画: Similar to a Japanese version of YouTube, this video-sharing website is incredibly popular with the Japanese Vocal Synth community. 

Nikokara/ニコカラ: A Nico Nico Douga supported service that displays Hiragana song lyrics across a video.
