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 WMA format?
WMA (Windows Media Audio) is Microsoft's proprietary audio compression format. It was designed for Windows devices and offers good quality for voice content on Windows platforms.
Is WMA better than MP3 for voice?
WMA can offer slightly better quality than MP3 at lower bitrates for voice, but MP3 has much wider device compatibility. WMA is best used when targeting Windows devices specifically for voice applications.
What bitrate should I use for voice?
128 kbps offers excellent quality for voice messages. Since AMR is telephony-grade (8kHz), higher bitrates won't significantly improve quality. 96 kbps is suitable for efficient voice storage, while 64 kbps works for basic voice archiving.
What devices support WMA?
WMA is best supported on Windows devices, Xbox, and Windows Media Player. Support on Mac, iOS, and Android devices varies and may require third-party apps. For wider compatibility with voice messages, consider MP3 or OGG.
