How to Convert Audio to WAV Online
What Is the Audio to WAV Converter?
The IndiPiano Audio to WAV Converter is a free online tool for preparing supported audio files as uncompressed WAV recordings for editing, music production and practice. Convert one recording or several files with control over bit depth, sample rate, channels and volume. Processing takes place on your device, with no audio upload, installation or login required.
Add Recordings and Trim the Audio
Select your files or drag them into the converter. Supported inputs depend on your browser and can include MP3, M4A, AAC, OGG, FLAC, WAV and WebM. Preview each recording, then drag across its waveform to select a section. Adjust the selection boundaries or enter start and end times to isolate a musical phrase, remove unwanted material or prepare a practice clip. Keep the full recording by leaving it untrimmed.
Choose WAV Format and Output Settings
Select 8-bit, 16-bit, 24-bit or 32-bit PCM, or choose 32-bit floating-point WAV for compatible audio software. Sample-rate options range from 8 to 96 kHz, with automatic selection also available. Keep the detected mono/stereo configuration or select either output explicitly. Adjust volume from 25% to 300% and apply fade-in and fade-out transitions of up to 30 seconds. These controls help match recordings to your editing or playback requirements.
Batch Convert and Download WAV Files
Convert files individually or process the queue with Convert all to WAV. Check the estimated output size and conversion progress, then download recordings separately or collect the completed files in a ZIP archive. Browser audio decoding, resampling and WAV encoding provide a flexible workflow for preparing piano recordings, rehearsal excerpts and audio for DAW import. WAV avoids further lossy encoding, but converting a compressed source or increasing its sample rate or bit depth does not recover lost audio detail.
