GSM to AMR

Useful information about GSM

Extension: GSM
Name: GSM File Format
Mime Type: GSM File Format
Converter: GSM Converter
Description: The .gsm file extension is used for an audio file format. A .gsm file is produced by the lossy CBR sound compression codec with a sample rate of 8000 samples/second, while its data rate is 13 Kbps. The .gsm file format is a global standard format for many mobile phones. These GSM files provide a practical compromise between file size and quality, making this file format an efficient standard for telephone-quality audio. - Source

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
