BUFFER SIZE OF I2S

[Shariff]

Hi Engineers,

I am developing an application which is kind of similar to an MP3 player.

I am reading an audio file of wav format from SD card using fatfs library f_read() function with buffer size of 1024 bytes.

and I am transmitting the buffer through i2s. What I found is the audio file is playing with more speed as expected and also experiencing

some pop and tick sounds. The clock configurations are all fine as LRCK is 44100, SWIDTH 16bit stereo.

I tried different sizes of buffer but still it didn't make any difference rather some speed variations.

Can anyone help me out solving this issue.

Thanks and regards,

Ajmal
