Why Convert WAV to AMR?
WAV stores uncompressed PCM audio — high quality but very large files (10 MB per minute at CD quality). AMR (Adaptive Multi-Rate) is a speech-optimized codec that compresses voice audio to as little as 50–100 KB per minute — a 98% reduction in file size.
Converting WAV to AMR is useful for telephony systems (IVR prompts, voicemail greetings), mobile messaging on bandwidth-limited networks, or any application where ultra-small speech files are needed. AMR is the standard voice codec for 3G mobile networks.

Frequently Asked Questions
Is AMR suitable for music?
No. AMR is designed for speech at 8 kHz. Music will sound heavily distorted. For music, convert to MP3 or M4A instead.
How small will the AMR file be?
A 10 MB WAV voice recording typically converts to ~100–150 KB in AMR — roughly 98% smaller.
Can I batch convert multiple WAV files?
Yes. Upload multiple files and download AMR results individually or as a ZIP archive.
What devices play AMR files?
Most Android phones, VLC, and telephony systems. iOS requires a third-party app.
