STA013 MPEG 2.5 LAYER III (MP3) SOURCE DECODER

https://www.rpi.edu/dept/ecse/mps/6526-STA013_AppNote.pdf

The STA013 is an MPEG 2.5 Layer III Audio Decoder capable of decoding elementary streams from 8 up to 320 Kbit/sec. The full sampling frequencies range is supported, from 8 up to 48 KHz. For this reason we use the name "MPEG 2.5". • Supports all ISO Layer III Functionalities and WorldSpace Extensions. • Programmable Input Data Interface.

MPGEDIT - MPEG 1 / 2 / 2.5 (MP3) Audio File Editor

http://www.mpgedit.org/mpgedit/index.html

mpgedit is an MPEG 1 layer 1/2/3 (mp3), MPEG 2, and MPEG 2.5 audio file editor that is capable of processing both Constant Bit Rate (CBR) and Variable Bit Rate (VBR) encoded files. mpgedit can cut an input MPEG file into one or more output files, as well as join one or more input MPEG files into a single output file. Since no file

There is an unofficial MPEG-2.5 which is rarely used. also covered. MPEG-1 audio(described in ISO/IEC 11172-3) describes three Layers of audio coding with the following properties: one or two audio channels sample rate 32kHz, 44.1kHz or 48kHz. bit rates from 32kbps up to 448kbps Each layer has its merits.

This chapter describes the MPEG-2 Audio coding family which was developed to extend the MPEG-1 Audio functionality to lower data rate and multichannel applications. First we will discuss MPEG-2 LSF and “MPEG- 2.5” systems in which lower sampling frequencies were used as a means to reduce data rate in MPEG-1 audio coding.

Note: MPEG Version 2.5 was added lately to the MPEG 2 standard. It is an extension used for very low bitrate files, allowing the use of lower sampling frequencies. If your decoder does not support this extension, it is recommended for you to use 12 bits for synchronization instead of 11 bits. C 2 (18,17) Layer description 00 - reserved
