WAV to AAC Without Quality Loss
Converting WAV to AAC involves lossy compression. Some data will be discarded. Use a high bitrate to keep loss minimal and nearly inaudible.

WAV stores audio without any compression artifacts. AAC uses perceptual coding to reduce file size. The encoder discards audio data it predicts you won't hear.
At 320kbps, most listeners can't distinguish AAC from the lossless source in blind tests. Use the highest bitrate your use case allows.
AudioUtils lets you pick the output bitrate. Choose 320kbps for near-transparent quality. Choose 128kbps for smaller files when size matters more than fidelity.
Frequently Asked Questions
Is AAC better than MP3 for compressing WAV?
Yes. AAC produces better audio quality than MP3 at the same bitrate. At 128kbps, AAC sounds roughly equivalent to 192kbps MP3. It's the more modern, efficient codec.
What bitrate should I use for AAC?
128kbps for good quality at small file sizes, 192kbps for high quality, 256kbps for near-transparent quality. AAC is efficient enough that even 128kbps sounds great.
What's the difference between AAC and M4A?
AAC is the codec (compression method). M4A is a container file that typically holds AAC audio. The audio quality is identical — the difference is just the file wrapper.
About WAV
