ADSP-BF518 MP3 codec is not supporting for all frequency of audio signal. Request to share if there is any reference code which can help to process audio signal working in Any frequency
Just wondering which code are you referring to? Is it something provided by ADI?
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.
