WAV to M4R Converter

Convert WAV to M4R online for free. Change audio format for playback, editing, uploads, podcasts, ringtones, archiving, or a better balance between file size and sound quality.

Converting WAV to M4R re-encodes the audio using the target codec. Sample rate and channel layout are preserved, and ID3 metadata (artist, title, album art) carries over. File size and quality depend on the M4R codec — lossy targets shrink size; lossless targets preserve every sample.

About the WAV Format

WAV (Waveform Audio File Format) is an audio file format jointly developed by Microsoft and IBM in 1991. It stores raw, uncompressed audio data using Pulse Code Modulation (PCM), preserving the complete audio signal exactly as recorded. WAV is the standard working format used in professional recording studios and digital audio workstations such as Pro Tools, Logic Pro, and Ableton Live.

Because WAV files contain uncompressed audio, they are very large — approximately 10 MB per minute of stereo audio at CD quality (44.1 kHz, 16-bit). This makes WAV impractical for distribution or streaming, but ideal for recording, editing, and mastering where no quality compromise is acceptable. WAV files are universally supported across all platforms and audio software, making them the most reliable format for professional audio work.
