AIFF to FLAC for Music Production

FLAC is a session format, which is exactly what you want. It imports into Pro Tools, Logic, Ableton, Reaper, and FL Studio with no re-encoding, scrubs instantly, and cuts sample-accurately — no decode step sitting between you and the waveform.

Sample rate and channel layout are preserved exactly — stereo stays stereo, 48 kHz stays 48 kHz, and nothing is silently resampled behind your back. That matters when you are lining audio up against picture or against other stems.

Never send an MP3 to a distributor or streaming platform. They transcode whatever you upload into their own formats, so handing them an already-compressed file stacks a second lossy generation onto what your listeners actually hear. Deliver lossless; convert to lossy for humans.

Disk usage barely moves — this conversion buys compatibility rather than space. Every sample makes it across intact. The only thing that changes is the container.

AIFF is the format of Logic Pro and GarageBand bounces. It plays where it was made, but AIFF is uncompressed like WAV, so a four-minute song is 40 MB+ and won't attach to an email. FLAC is the destination when you need uncompressed, edit-ready audio that every DAW and editor accepts. Expect a similar file size; the reason to convert is playback and workflow, not disk. Both AIFF and FLAC are lossless, so this specific conversion is bit-perfect: every sample survives and you can go back to AIFF later without any loss.
