AMR to OPUS

Useful information about AMR

Extension: AMR
Name: Adaptive Multi-rate Codec File
Mime Type: audio/amr
Converter: AMR Converter
Description: An AMR file is an audio file saved in a compressed audio format developed by Ericsson. It is optimized for storing spoken audio and is used by many 3G cell phones to store voice recordings, which include MMS messages. AMR files incorporate the Algebraic Code Excited Linear Prediction (ACELP) algorithm, which is designed to efficiently compress human speech audio. AMR files may be saved in either the AMR-NB (Narrowband) or AMR-WB (Wideband) format. Wideband audio supports a broader frequency range and therefore provides better sound quality. - Source

Useful information about OPUS

Extension: OPUS
Name: Opus File Format
Mime Type: audio/ogg | audio/opus
Converter: OPUS Converter
Description: Opus is a lossy audio coding format developed by the Xiph.Org Foundation and standardized by the Internet Engineering Task Force, designed to efficiently code speech and general audio in a single format, while remaining low-latency enough for real-time interactive communication and low-complexity enough for low-end embedded processors. Opus replaces both Vorbis and Speex for new applications, and several blind listening tests have ranked it higher-quality than any other standard audio format at any given bitrate until transparency is reached, including MP3, AAC, and HE-AAC.[ - Source
