Description
[ ALL FEATURES FREE & NO FULL-SCREEN ADS FOR BASIC USE ]
■ Basic Features (Pitch, Tempo & Formant): 100% FREE, with no full-screen ads during standard use. Adjust Pitch, Tempo, and Formant directly from the main-screen sliders.
■ Advanced Options: Also 100% FREE. Occasional full-screen ads may appear only when opening advanced settings. Permanent ad removal is available with a small one-time purchase.
This audio & video speed changer and pitch shifter lets you import MP4, MKV, WAV, and MP3 files, extract audio for waveform editing, and play or export as MP3/WAV while independently adjusting Pitch, Tempo, and Formant.
With A-B looping, playback marking, waveform editing, and vocal processing, it is ideal for music transcription, vocal practice, dance routines, language learning, and audio analysis.

Thank you so much. Now I can export audio in Wav format. This tool is really helpful. Love this app.

Final, I have found my dream app. I tried other apps before, but they were arrogantly doing jobs which were not even described in their given names. But this app only does what supposed to be done according to its name. It's really easy, fast and affordable to use. Its features are all accurate 100% and amazing. Thanks for the great job keep it up👍

Excellent and easy results. Pitch changing has never been so easy. Great work dear developers.
★☆☆☆☆suki· Mar 1, 2026
Terrible. So many ads, it's insulting. Terrible quality. Butchers the audio as well. DO NOT WASTE YOUR TIME.
★★☆☆☆Ian T. Mansan· Mar 15, 2026
Full of ads. Good ideas but most options bug out or conflict with each other. Recommend implementing a better algorithm overall as this is very amateur.
