Recommended Settings
For Voice Editing
- •16 kHz for native quality
- •16-bit depth for speech
- •Uncompressed for editing
For Speech Processing
- •16 kHz recommended for transcription
- •Compatible with speech recognition
- •Lossless voice quality
Pro Tips
- •AMR is 8kHz telephony-grade - higher sample rates won't improve quality
- •16-bit depth is optimal for speech content
- •WAV files will be larger but allow lossless editing

Frequently Asked Questions
What is AMR format?
AMR (Adaptive Multi-Rate) is a telephony-grade audio codec optimized for speech encoding at 8kHz. It's commonly used in WhatsApp and Telegram voice messages. AMR is mono and designed for voice, not music.
What is WAV format?
WAV (Waveform Audio File Format) is an uncompressed audio format developed by Microsoft and IBM. It stores audio in its raw, unprocessed form without any quality loss.
What sample rate should I choose?
16 kHz (native) is recommended for most voice applications as it preserves the source quality. 22.05 kHz or 44.1 kHz can be used for compatibility, but won't improve quality since AMR source is 8kHz telephony-grade.
Why only 16-bit option?
AMR is a telephony-quality speech codec, so 16-bit is sufficient to capture all available audio information. Higher bit depths (24-bit, 32-bit) would be overkill for speech content and unnecessarily increase file size.
Why are WAV files so large?
WAV files are uncompressed, storing audio in its raw form. While the file will be larger than the original AMR, it allows for lossless editing and processing of voice recordings.
