Online audio tools

IndiPiano brings together eight free online audio tools for musicians, singers and content creators. Change pitch and speed, analyse songs, extract audio from video, trim recordings, compress MP3 files and convert audio formats directly in your browser. Choose a tool from the grid above, upload your file and follow its controls. No software installation or login is required.

Audio Pitch and Speed Changer

Upload your audio to change its pitch or playback speed. Transpose a song to suit your vocal range or slow down a difficult passage for music practice. Adjust pitch and tempo independently, preview the result and download the processed audio.

Chord Detector

Upload a song or recording to identify chords and explore them on a timeline. Choose Simple, Intermediate or Extended chord results, review piano and guitar diagrams, and explore alternative suggestions. Use this online chord detector to support learning songs, arranging music and playing along.

Key, BPM and Time Signature Detector

Analyse a recording to estimate its musical key, tempo in beats per minute (BPM) and time signature. These results help with practice, arranging and matching tracks. Time signature detection works best with regular rhythms; results may vary for complex or unusual meters.

Extract Audio from Video

Upload a video to extract its audio for a separate sound file. Preview the recording and select the section you want to keep before exporting. This video-to-audio tool is useful for working with recorded performances, interviews and other video soundtracks.

Audio Cutter

Trim an audio file by selecting the start and end of the section you need. Preview your selection and download the clip. Use the online audio cutter to remove unwanted beginnings or endings and prepare shorter recordings for practice or content creation.

MP3 Compressor

Reduce MP3 file size to make recordings easier to store and share. Upload your file, choose the available compression settings and download the compressed version. Higher compression can reduce audio quality, so select a balance that suits your recording.

MP3 Converter

Convert supported audio files to MP3 for convenient playback and sharing. Upload a recording, select the available output settings and download the converted file. MP3 is useful when you want a smaller audio file for everyday listening.

WAV Converter

Convert supported audio files to WAV for editing and music production. Upload your recording and download it in WAV format for use in compatible audio software. Converting an MP3 to WAV does not restore sound detail lost during MP3 compression.
