About the M4A to WAV
M4A is the AAC audio format used by iPhone voice memos, iTunes and many podcasts. Some car stereos, older players and editors can't play it. WAV is uncompressed audio: perfect quality but around 10 MB per minute, which makes it awkward to email or upload.
FileStripe decodes your M4A file with your browser's built-in decoder and encodes WAV on your device. Your files are never uploaded, so it is quick even for long recordings.
