Get Wideband AMR Recorder (High Compression Voice) old version APK for Android
One-touch Wideband AMR recording!
Record hours of MP4 audio using only a fraction of the disk space other recorders use while retaining acceptable voice clarity! The MP4 audio files this app produces are ultra portable for easy sharing!
WHY AMR?!
If you think AMR audio sounds bad, you haven't had the chance to experience WIDE-BAND AMR! Hearing is believing, and the storage space savings will astound you!
Remember, AMR (Adaptive Multi-Rate) was designed and tuned to capture only sounds emitted from the human vocal tract. Other codecs like AAC and MP3 were designed for full spectrum audio recording, therefore this app is not recommended for those wishing to record live music or sound effects.
