AudioRetoucher is a powerful tool for musicians and audio engineers looking to make adjustments to their tracks in real-time. The software is designed to change the pitch and tempo of a sound track, making it a great option for those looking to modify vocal or instrumental tracks for live performance.

One of the key features of AudioRetoucher is its real-time processing capabilities. Using state-of-the-art algorithms, the software allows you to adjust the tempo and pitch directly during playback. This allows for fine-tuning of sound settings before saving the final file.

Another important feature of AudioRetoucher is its ability to shift the key of a track. The software offers a crisp pitch-shifting function, allowing users to change the pitch of a song from -12 to +12 semitones without any audible artifacts. This makes it a great option for singers looking to match the key of a backing track to their own voice, or for DJs looking to create seamless harmonic mixes.

The software also includes a time stretching feature, which allows for automatic detection of the tempo of a song and the ability to adapt it to your needs. This can be particularly useful for DJs looking to make the music tempo suitable for dancing and create playlists with beatmatching.

In addition to these features, AudioRetoucher also includes a speed adjustment function that allows for slight changes to the playback speed. This can be useful for situations where the audio track is out of sync with the video, or when changing video format between 24fps and 25fps.

Another great feature of AudioRetoucher is the ability to adjust the bass and treble after changing the tempo and pitch. This allows for fine-tuning of the timbre of the sound, ensuring that the final result is exactly as desired.

The software also supports Karaoke MP3+G files, meaning that the graphic part of the song will be adjusted, so the lyrics of the song will be synchronized with the music after changing the tempo and speed. Additionally, the software offers several voice effects, allowing users to experiment with different sounds and create unique effects.

In terms of supported audio formats, AudioRetoucher can handle most popular formats such as MP3, M4A, FLAC, WAV, and AIFF. After processing, the files are saved in MP3, WAV, FLAC or M4A format and all the audio tags will be copied to the output file.

All in all, AudioRetoucher is a powerful tool for musicians and audio engineers looking to make adjustments to their tracks in real-time. With its real-time processing, key shifting, time stretching, and other features, it's a versatile tool that can help take your audio to the next level. The software is compatible with Windows Vista, Windows 7, Windows 8, Windows 8.1, Windows 10, Windows 11.
