Convert WAV to M4A
What is WAV?
WAV
WAV stores uncompressed PCM (Pulse Code Modulation) audio as raw waveform samples, typically 16-bit or 24-bit at 44.1kHz or 48kHz sampling rates. Also supports compressed formats like MP3 or AAC as payload. Standard CD audio uses 44.1kHz/16-bit stereo. Provides lossless audio quality without psychoacoustic compression. Converting between audio formats may involve compression (WAV→MP3) or decompression (MP3→WAV).
- WAV encodes audio using lossless compression at various bitrates
- Lossless audio data provides full fidelity for M4A conversion
- Sample rate and bit depth preserved or downsampled for M4A compatibility
What is M4A?
M4A
M4A is MPEG-4 Audio container typically storing AAC or ALAC compressed audio. Part of MP4 family using .m4a extension for audio-only files. Supports metadata tagging, chapter markers, and album artwork. Better quality than MP3 at equivalent bitrates when using AAC codec. Default format for iTunes purchases and Apple Music downloads. Maximum 6GB file size.
- M4A encodes audio using lossy compression at various bitrates
- Lossy source limits WAV quality ceiling—cannot restore removed frequencies
- Sample rate and bit depth preserved or downsampled for WAV compatibility
Why Convert WAV to M4A?
✓ Workflow Integration
M4A format integrates seamlessly with industry-standard software and workflows, ensuring compatibility with professional tools and established production pipelines.
✓ Storage Optimization
