Frequently Asked Questions

Why convert M4A to WAV? +
WAV is an uncompressed, universally recognized format ideal for professional audio editing and mixing. Converting your M4A recordings (such as iPhone voice memos) to WAV ensures maximum compatibility with software like Pro Tools or Audacity.
Does converting to WAV improve the M4A quality? +
No. You cannot magically 'restore' lost quality from a compressed M4A file. The resulting WAV file will sound exactly the same as the M4A, but it will be in an uncompressed format suitable for editing without further generation loss.
Why is the resulting WAV file so much larger? +
M4A uses advanced compression to keep file sizes small. WAV files store raw, uncompressed audio data (typically at 1411 kbps), so the resulting file will be significantly larger—often 5 to 10 times the size of the M4A.
