USE CASE
I tried singing, a short video, and voice recording. You can use it only where you need it.
Free planRecord a backing track and vocals, tune pitch and formants, choose a MIX such as Studio or Radio, then export the range you need to WAV/MP3.
Paid plansUnlock two harmony generators, three noise processors and distribution-ready mastering. Set pitch, volume, pan and stereo width per harmony.
Free planRecord to any vocal track, trim the gaps and shape the tone with Radio/Studio MIX and formants.
Paid plansReduce room noise, lip noise and sibilance from a silent section before MIX, then deliver a polished WAV.
Free planCombine note-by-note pitch movement and formants for a brighter or fuller character, with detailed timing edits.
Paid plansLayer two theory-aware harmony systems for fairy, chorus or alter-ego textures, then spread them across the stereo field.
*Formant/pitch correction is audio editing after recording. It is not a voice changer for real-time calls.
Start recording and editing instantly. Link a Google account when you want cloud save, cross-device access and recovery; browser-only saving remains available without sign-in.
Start linking with GoogleLoad MP3, WAV, M4A, AAC, FLAC, OGG, WebM or MP4 files your browser can decode. Paid plans can also stream YouTube accompaniment. Switch the timeline between seconds and bars.
Arm a vocal track, record, then drag the clip to another track if you need to rearrange it.
Edit pitch, rhythm, note length and formants note by note.
Choose from five MIX presets. Paid plans add three noise processors and two harmony systems.
Export WAV or MP3 in mono or stereo, with range export. Every user gets 48 kHz/24-bit WAV by default and 44.1 kHz/16-bit as a compatibility option; paid plans add hi-res export and mastering.
SMARTPHONE
The smartphone version shows the recording process, YouTube linkage, and track editing in a large format. The timing of an audio 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.
🎉 Goal achieved: cumulative paying users passed 1,000! Free pitch correction is extended by two months through October 31, 2026. Rhythm correction (auto-align, horizontal note movement, and note-length editing) remains paid-only.
Arm any vocal track with its R button. Paid plans can apply environment, lip and sibilance cleanup to the dry take before mixing.
Backing track
Vocal 1 · R ●
Paid: environment / lip / sibilance
Choose from five presets: As is, Studio, Hall, Radio and Whisper. Every preset analyses level, peaks and dynamics to shape gain, EQ and compression automatically—and you can fine-tune the ambience.
Export WAV/MP3 in mono or stereo, including a selected range. Every user gets 48 kHz/24-bit WAV by default, with 44.1 kHz/16-bit for compatibility. Paid plans add 96/192 kHz WAV and automatic mastering.
Set BPM and meter, then change tempo or meter anywhere in the song. Paid plans can analyse a backing track and estimate its BPM automatically.
Paid plans stream the official embedded player for recording practice. Toggle visibility, mute or solo it as needed. YouTube video and audio are never saved or included in exports.
Set A and B points to loop a tricky phrase, add fades from the clip handles, and export just that range to WAV/MP3. Clear the loop whenever you are ready for the full take.
When singing or speaking feels stuck, a friendly AI chat suggests simple exercises. The free plan includes up to three chats a day; paid plans include ten.
Set a key, scale and mode, then generate upper or lower harmonies in 1–2 octaves. Paid plans let you adjust volume, pan and stereo width for each harmony system.
Key: A minor
Harmony 1 · +3rd · Volume 52%
Harmony 2 · −Octave · Width 35%
On a PC, you can centrally display recordings, YouTube, tracks, and pitch. On smartphones, recording, YouTube linkage, track recording/editing are displayed in a large size, with move/crop controls, a bottom ruler, and an export progress popup.

Development support
Kawaii REC is a personally developed app born from the desire to support future artists. We have set the price as affordable as possible so that it can reach students and those who are pursuing their dreams with all their might. If you can afford it, please support this project with an annual plan, one-off purchase, or a donation, so that we can make recording, correction, and MIX easier to understand and more cute.
Donations are voluntary support, and there are no additional features, return gifts, or paid plans available.

You can load audio files that your browser can play and decode, such as MP3, WAV, M4A, AAC, FLAC, OGG, WebM, and MP4. Actual compatibility varies depending on browsers and devices such as Chrome, Edge, Safari, etc. If you are unable to read the file, please convert it to MP3 or WAV and try again.

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 an accessible price. We focus on a practical, dependable workflow rather than trying to cover every possible format or replicate a full commercial studio. For productions that require professional quality, please consider using a DAW such as Pro Tools, Cubase, or Fender Studio, or working with a professional sound engineer. Since it runs in a web browser, behavior may vary with the browser, OS and device performance. We recommend Windows or Mac with plenty of memory and a large screen. Keep a separate copy of important original audio and save your project regularly.
Kawaii REC promotional ambassador: Nanoha.
Whether I'm recording voice acting or singing, it used to take time to launch software and choose effects. Now I can start in three seconds from a browser bookmark, with the tools I need to finish the audio myself.
