I have a project to generate audio using a codec. I will store the audio data in hex format on my nrf52 device and with the aid of the i2s interface, I will send the hex data to a audio codec which will then convert it to audio.
I have finished the whole programme and tested it. I am getting audio at the output but is is not exactly like the audio i recorded so I am not sure if the hex data I have is correct. I got the data by recording the sample audio with audio city then i used a hex software to convert the PCM data to hex data. But I am not sure if the hex data is correct.
The PCM audio is meant to have a sampling rate of 8KHz, mono and 16 bits.
Thanks.
