ADSP-BF518 MP3 codec

Just wondering which code are you referring to? Is it something provided by ADI? 

Hi Jithul,

Yes we where using MP3_Decoder_BF-REL3.1.1_PROD -  drivers  which is downloaded from ADI website. Here customer is not finding the code working for all the frequencies. Request to suggest if any latest drivers available to resolve this issue.

An SR has been logged through private support for this issue, and will continue to be dealt with through that channel. We will post the outcome here, if appropriate.

Hi,

The software modules which are available currently are listed in the below link:

Also please note that the Blackfin MP3 decoder supports the following frequencies:

• All sampling frequencies as specified by [1] (ISO/IEC 11172-3, a.k.a. ‘MPEG1’, 32, 44.1,and 48kHz) and [2] (ISO/IEC 13818-3, a.k.a. ‘MPEG2’, 16kHz, 22.05kHz, and 24kHz)
• Support for sampling frequencies of 8kHz, 11.025kHz, and 12 kHz (for an unofficial standard, widely known as ‘MPEG2.5 MP3’)
