I want a matlab code for converting audio into binary for wireless transmission .

hey, Im doing a project in communication system in which i have to transmit a audio by a transmitting kit which is connected to a function generator. So, i want code which convert audio into binary and then at reciever side , it convert the recieve binary data into audio . But limitation is that function generator only handle 100k bits size file . so it should below 100k bits

Hi,

You can reduce the audio file size by downsampling or decimating the audio sampling rate. For information on how to perform downsampling or decimation, you can refer to the following links:-

Additionally, you can also split the audio into smaller segments (smaller than 100k bits) and then concat them at the receiver end.

To convert audio into binary format for transmission and convert it back into audio at the receiver side, you can utilize the solution in this MATLAB Central discussion:-
