Find your character.

Pick a starting point, then make the sound your own. Changing a control queues a new render; press Apply to hear it. Selected ranges affect exported audio, not your original file.

Pro finishing — gate, compression, fades & level

Optional, conventional DSP. Gate reduces quiet background; compressor controls peaks. These cannot isolate speech or repair severely damaged recordings.

What the controls do

Pitch and tempo are calculated separately; formant color uses an approximate spectral-envelope warp. Strong settings may add metallic or grainy artifacts, especially in music or noisy recordings.

03 / EXPORT

Keep the final take.

Export genuine uncompressed PCM WAV audio with your chosen precision. No watermark or upload.

WAV bit depth

Changing export precision requires applying again. A 24-bit file preserves more numerical precision; it does not restore detail lost from the source.

Process a recording to unlock export.

Peak/RMS levels appear after processing.

Made for creators

Character dialogue, narration variations, game prototypes, podcast sketches and playful voiceovers. For the cleanest results, start with a dry vocal recording and moderate settings.

GOOD TO KNOW

Voice design without the upload.

Does this use AI or clone identities?

No. These are mathematical audio effects, not identity cloning or text-to-speech. The app doesn’t need a model download or external API.

Can I use a long recording?

This lightweight edition supports up to 3 minutes and 18 million decoded samples. Large files and extreme pitch shifts can take longer or sound less natural.

Can it change formants independently?

The formant slider approximates vocal spectral-envelope changes independent of pitch. It does not offer the accuracy of advanced vocal-tract or neural vocoder systems.

What happens to my files?

Audio is decoded, modified and exported in your browser. The app doesn’t transmit recordings. Microphone recording is optional and requires browser permission.

Using Voice Changer Studio

Import or record audio, select a preset and adjust pitch, tempo or effects. Choose the full recording or a supported section, apply and compare before saving WAV. Recipe JSON stores settings rather than the source audio or selection.

This is conventional DSP, not voice cloning or neural identity conversion. Formant color and pitch/tempo algorithms are approximations that may introduce artifacts. Source/intermediate/output budgets and browser codecs apply; microphone use requires secure context and permission. A 24-bit export does not recover source detail. Settings/selection/bit-depth changes invalidate downloads until re-Apply. No streaming large-file decode or professional multitrack automation is supplied.

Apply conventional voice effects and review the WAV export

Load or record supported audio, adjust pitch, tempo and character effects, and preview the processed voice before exporting WAV. The effects are conventional DSP; the workspace does not clone an identity or generate speech from a model.

Example workflow

Keep the original recording and load a short supported sample or record a new take with microphone permission.

Adjust one effect at a time and compare the result with the source so artifacts are easy to notice.

Apply final settings, choose a supported WAV bit depth and export; re-apply after changing settings, selection or bit depth.

Authored example: Use a short line of dialogue and make a modest pitch change while keeping tempo fixed. Listen for artifacts and intelligibility before trying a character preset; label it as an effect, not a real speaker identity.

Limits: Formant color and pitch/tempo effects are approximations and can introduce artifacts. Microphone recording requires a secure context and permission. A 24-bit export does not restore source detail, and settings, selection or bit-depth changes invalidate a previous download until re-apply. Large-file decoding and multitrack automation are not supplied.

Voice Changer Studio questions

Does Voice Changer clone a real person's voice?

No. It applies conventional pitch, tempo and character effects; it does not perform identity cloning or model-based speech synthesis.

Why did the previous export become unavailable after I changed a setting?

Changing settings, selection or bit depth invalidates the prior export. Re-apply processing before downloading the updated WAV.
