Why should I convert WAV files to AAC format?

Converting WAV to AAC reduces file size significantly while maintaining good audio quality, making it ideal for streaming, mobile playback, and digital music distribution.

Is the audio quality the same after converting WAV to AAC?

No, AAC uses lossy compression, so some original audio information is lost during conversion, but it is optimized for perceptual quality at smaller file sizes.

Can I use raw .aac files for tagging and chapters?

Raw .aac streams have limited metadata support. For tagging and chapters, using MP4 or M4A containers with AAC audio is recommended.

Converts audio to AAC, a widely supported lossy format with efficient compression
Produces output suitable for streaming, mobile playback, and digital distribution
Browser-based and easy to use without software installation
Offers conversion profiles like AAC-LC and HE-AAC for different quality and bitrate needs

Examples

Mastering engineers convert archived WAV mixes into AAC-LC M4A files for digital storefront upload
Streaming services compress WAV assets to HE-AAC for low-bitrate mobile streaming
Content creators encode WAV audio tracks into AAC to embed within MP4 video files

Common Use Cases

Reducing large WAV files to smaller AAC files for streaming and bandwidth efficiency
Converting high-fidelity recordings into format compatible with smartphones and portable players
Encoding broadcast-ready audio suitable for digital radio and internet streaming platforms

Tips & Best Practices

Select the appropriate AAC profile based on your target playback device and quality needs
Use MP4 or M4A containers when metadata tagging or chapters are needed
Remember that AAC is lossy, so retain WAV files as masters for archival
Verify compatibility of AAC files with older devices before distribution

Limitations

Converting from WAV to AAC is a lossy process and cannot preserve bit-perfect original audio
Not all AAC profiles are supported on all devices, especially older hardware
Raw .aac streams do not support rich metadata tagging; containers like MP4/M4A are preferred
Licensing and patents may affect encoder availability and distribution options
WAV files are large, requiring sufficient processing and storage during batch conversions
