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 OGG format?
OGG is a free, open-source container format that typically uses Vorbis for audio compression. It offers quality comparable to MP3 but is completely patent-free, making it ideal for voice message sharing.
What quality level should I use for voice?
Quality 3 (≈112 kbps) provides excellent quality for voice messages and speech. Since AMR is telephony-quality (8kHz), higher quality levels like 7 or 10 won't significantly improve quality as the source is bandwidth-limited.
Why are high quality levels not recommended?
AMR is a telephony-quality format (8kHz sample rate, mono) designed for voice, not music. Quality levels above 5 are overkill for speech content and create unnecessarily large files without perceptible quality improvement.
Can I use OGG for voice messages?
Yes! OGG Vorbis is completely free and open-source with no licensing fees or patents, making it ideal for sharing voice messages in open-source applications, web platforms, and cross-platform voice communication.
