How to Convert WAV to AIFF
WAV is the Windows production standard; AIFF is macOS's native lossless format. Both are uncompressed PCM audio with identical quality — but some Apple software and older macOS tools prefer AIFF. When you move a project from a Windows DAW to Logic Pro or need to import audio into Final Cut Pro, converting WAV to AIFF ensures seamless compatibility. This guide covers the workflow and when it actually matters.
WAV vs. AIFF: Are They Actually Different?
Technically, WAV and AIFF are nearly identical formats. Both store raw PCM audio samples. Both support the same bit depths (8-bit, 16-bit, 24-bit, 32-bit float) and the same sample rates (44.1 kHz, 48 kHz, 88.2 kHz, 96 kHz, 192 kHz). The difference is structural: WAV uses the RIFF container (developed by Microsoft), while AIFF uses the IFF container (developed by Apple and Electronic Arts). Metadata handling differs slightly — AIFF stores markers and instrument data in a format Logic Pro understands natively. Audio data itself is bit-for-bit identical when both files use the same bit depth and sample rate. Converting between them introduces no quality change whatsoever.
When to Convert WAV to AIFF
Most situations do not require conversion. Logic Pro X, GarageBand, and Final Cut Pro all import WAV files without issues. If you open a WAV file in Logic Pro, it works. However, some specific scenarios warrant conversion: older versions of Pro Tools (pre-2019 on Mac) preferred AIFF for multi-channel sessions. Some hardware samplers and the Akai MPC ecosystem historically worked better with AIFF than WAV. Older macOS utilities and some audio plugins written for Classic Mac OS may require AIFF. If someone hands you a project template or session file that explicitly references AIFF files, renaming the WAV won't work — the container format must actually match.
Step-by-Step: WAV to AIFF Conversion
Upload your WAV file to AudioUtils in any browser — Safari on Mac is ideal for the smoothest experience. The file is processed locally; no audio leaves your computer. Select AIFF as the output format. Since both formats are lossless, there are no quality settings to choose — the output will be bit-perfect audio in an AIFF container at the same sample rate and bit depth as the source. Large WAV files (a 30-minute session at 24-bit/96 kHz can be 300+ MB) process in the browser; depending on your machine, this may take 30–60 seconds. Download the resulting .aiff file and verify it in Finder — AIFF files show a distinctive waveform icon on macOS and can be previewed directly in QuickLook.
Importing Converted AIFF into Logic Pro
Logic Pro X accepts AIFF files natively at all bit depths and sample rates. Drag the AIFF file from Finder into the Logic Pro timeline or into the Project Audio Browser (press F to open it). If the file's sample rate differs from the project sample rate, Logic will prompt you to convert it or use it as-is. Always match sample rates to avoid pitch shifting — convert the file to the project's sample rate first. For a 44.1 kHz WAV being imported into a 48 kHz Logic project, re-export from AudioUtils at 48 kHz. Logic can resample internally, but doing it explicitly gives you more control and keeps the project clean.
Windows to Mac Production Workflow
Moving an entire project from FL Studio or Ableton on Windows to Logic Pro on Mac requires a structured approach. First, consolidate all audio regions in your Windows DAW — export every track as a separate WAV file at the project's bit depth and sample rate. Organize them with clear names (TrackName_Stem_v1.wav). Transfer to Mac via USB drive, network share, or cloud storage. Convert any WAV files that specific Logic instruments or plugins require as AIFF — in most cases, none will need conversion, as Logic handles WAV natively. Convert MIDI tracks separately; MIDI is DAW-agnostic. The main friction in cross-platform moves is plugin compatibility, not audio format differences.
