LinksConverterConvert an Apple M4A audio file into uncompressed WAV for editing in a DAW, sampling, or any tool that requires PCM audio. Note that WAV cannot add back detail M4A already discarded.
M4A is an AAC audio stream wrapped in an MP4 container. iTunes and Apple Music downloads ship as M4A, as do voice memos from iPhone. M4A files are smaller than MP3 at equal quality, but a small number of older car stereos and Bluetooth devices still expect the .mp3 extension.
WAV is uncompressed PCM audio — the same lossless signal a CD or studio session uses. A three-minute WAV is roughly 30 MB versus 7 MB for MP3, but every sample is preserved. Use WAV when you plan to edit, master, sample, or archive the audio and need zero generation loss.
