What file is the AMR file?

Amr player is a AMR MP3 format converter that allows users to convert AMR files. AMR (Adaptibve multi-rate) is a format that is widely accepted by major handset manufacturers to keep phone recordings. Because the capacity of the AMR file is small--the AMR audio size can be controlled at around 1K per second, even a 1-minute audio file can meet the technical specifications of China Mobile's current MMS no more than 50K, so AMR is the only format to add a manned voice to MMS. However, the same is because the "head" small, amr format song sound quality is conceivable, compared to the WAV ringtones, AMR ringtones volume, clarity, level sense is not at all a grade.
Using AMR Player is very simple, click the "Add File" button in the main interface, select one of the "Amr" files, and then click the "Play" button, the company player can decode the AMR audio file, and then play the audio/music for you. If you want to convert AMR to MP3 format, just select an AMR file, you add it, click "Amr to MP3", enter a MP3 file name, free program can turn mp3 file once for AMR.

AMR file format

The AMR file format is extremely simple, as shown in Figure 1:
Header with 6 bytes at the beginning of the file,
[#! AMRN] the section between brackets
(or hexadecimal is represented as 0x2321414d520a).
The next step is a continuous speech frame,
Each frame contains a frame head + speech data
The frame header is shown in Figure 2:
P set to 0
FT is encoded, and the available values are enumerated above.
Q is a frame quality indicator and if 0 indicates that the frame is corrupted, the recipient needs to set the Rx_type to Speech_bad or Sid_bad.
What is Rx_type please refer to RFC3267, in fact, the content of this section can be found in RFC3267.
Figure 3 This chart is a 5.9 kbit encoded file format (with 118 speech bits)
where P is a complement of 0 digits.
AMR (Audio/modem Riser, Voice/modem card) is an open industry standard that defines an expansion card that can support both sound and modem functions. This kind of design can effectively reduce the cost and simultaneously solve some limitations on the function of voice and modem subsystem.
