USE CASE
I tried singing, a short video, and voice recording. You can use it only where you need it.
Even if it's freeRecord the accompaniment and voice and adjust pitch, rhythm, and formant. You can select a MIX such as "Studio" or "Radio" and export only the required range to WAV/MP3.
If it is a paid version2 systems of automatic harmonization according to key and scale, 3 types of noise processing, and mastering for distribution. You can adjust the pitch, volume, pan, and left/right split for each harmony.
Even if it's freeRecord to any vocal track and trim unnecessary parts. Radio/studio MIX and formants can be used to adjust the sound to suit the role.
If it is a paid versionApply environment, lip, and sibilance processing from the silent section before MIX. It can be delivered as is in WAV.
Even if it's freeCreate a brighter, thicker voice by combining note-by-note pitch movement and formant adjustment. You can also edit the rhythm and length in detail.
If it is a paid versionUsing multiple tracks and two types of harmonies, we created an overlapping sound that resembles a fairy, chorus, or alter ego. You can also create a spread by splitting the left and right sides.
*Formant/pitch correction is audio editing after recording. It is not a voice changer for real-time calls.
You can try recording and editing right away. To save to the cloud and open from another environment, you need to log in with your Google account. Saving in the browser can be used without logging in.
Start linking with GoogleAudio files (formats that can be played and decoded by the browser, such as MP3 / WAV / M4A / AAC / FLAC / OGG / WebM / MP4) or paid version YouTube streaming cooperation. The timeline supports second/measure display.
Record to the track that is in recording standby. After recording, you can drag it to another track.
Adjust the pitch, rhythm, length, and formant of each note.
5 types of MIX. The paid version also includes 3 types of noise processing and 2 systems of harmonization.
To WAV/MP3. You can choose monaural or stereo, and the paid version supports high-quality WAV of 48kHz/24bit or higher and automatic mastering.
SMARTPHONE
The smartphone version shows the recording process, YouTube linkage, and track editing in a large format. The rhythm of the sound source clip can be adjusted using the "Move" tool in the center, and the start/end position can be adjusted using the "Crop" tool on the left and right edges. The seconds/measure ruler is displayed above and below, and you can play from the position you tap.
*Manual editing of pitch/rhythm correction requires detailed operations, so we recommend using it on Windows/Mac.
Move the note up/down, left/right in the pitch view, and drag the edges to adjust the length. In addition to division, detailed manual editing, automatic correction of "smooth" and "kerokero", you can use formants to create a thick to bright voice.
Launch offer: pitch correction is free until August 31, 2026. Rhythm correction (auto-align, horizontal note movement, and note-length editing) is paid-only. The free pitch-correction period extends by two months each time cumulative paying users reach another 1,000-user milestone.
Specify the recording destination with the R button of each vocal track. In the paid version, you can apply environment, lip, and sibilance individually to the dry sound source before mixing.

Paid environment / lip / sibilance
There are 5 types: ``as is'', ``studio'', ``hall'', ``radio'', and ``whisper''. For options other than "as is", the volume, peaks, and dynamics are analyzed and automatic gain, EQ, compressor, etc. are applied. You can also adjust the amount of resonance.
Supports WAV/MP3, monaural/stereo, and range export. The free version allows you to choose 44.1kHz/16bit WAV and MP3 192kbps, and the paid version allows you to choose high-quality WAV of 48kHz/24bit, 96kHz/24bit, 192kHz/24bit and automatic mastering.
In addition to the basic BPM and time signature, you can also change the tempo and change the time signature during the song. In the paid version, you can analyze the loaded accompaniment and automatically estimate the BPM.
The paid version of YouTube cooperation allows streaming playback with the official embedded player. It supports display/hide switching, mute/solo, and can be used as accompaniment during recording. Video and audio will not be saved and will not be included in the export.
Specify the A/B position and play the parts you are weak at in a loop. You can create fade ins and outs using the top left/top right handles of the clip, and export only the set range to WAV/MP3. You can clear the loop range later.
If you have trouble singing or speaking, a friendly and polite AI chat will suggest simple exercises. The free version allows you to consult up to 3 times a day, and the paid version allows you to consult up to 10 times a day.

Kawaii REC is a web recording app developed by one developer (Yuri Mashiro). We prioritize easy-to-understand, fun, and quick operation so that as many people as possible can express themselves at a cheaper price. Therefore, we do not aim to fully support a wide range of sampling rates, bitrates, and data extensions, or to provide professional studio-quality effects. For productions that require professional quality, please consider using a DAW such as Pro Tools, Cubase, or Fender Studio, or using a professional sound engineer. Since it runs on a web browser, its behavior may vary depending on the browser, OS, and device performance. Basically, we recommend using Windows/Mac with plenty of physical memory and a large screen. Please keep the original data of important sound sources separately and save them frequently while working.
Kawaii REC promotional ambassador: Nanoha.
Whether I'm working as a voice actor or singing, it takes a lot of time to start up recording software and choose effects. However, I can start recording in 3 seconds just by clicking on the bookmark in my usual browser, and it has enough effects that I want, so I was able to save a lot of time and complete the sound source by myself!

Developer: Yuri Mashiro
Until now, I have been active in various areas of the sound-related doujin scene, including as a singer, voice actor, VTuber, mixer, Vocaloid P, etc. This app was created by condensing all the creative experiences I had there. Recording software is easier, cuter, and better! Enjoy this app and share your shining voice with the world!
