WAV vs AAC — Key Differences

WAV is uncompressed and preserves every detail of the audio signal, making it the gold standard for recording and editing. The trade-off is large file sizes. AAC is a modern lossy format that compresses audio efficiently, achieving excellent quality at a fraction of the file size.

For professional production, keep files in WAV until you are ready to distribute. For distribution to Apple devices, streaming platforms, or storage-constrained environments, convert to AAC.
