Most free converters add watermarks or throttle quality. AudioUtils does neither. You get the same output quality whether free or paid.
Free users get 5 conversions per month with a 10-second preview output. The conversion engine is identical to Pro — same speed, same quality, same privacy. Upgrade for full-length output.
Your files stay on your machine. Nothing is uploaded. WAV is lossless. Converting to AAC reduces file size at the cost of some audio data. Use a high bitrate to minimize loss.
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.
