Regarding PCM buffer data used in audio loop example of bluecoin

[Dinakaran Palani]

how can i store 1 second audio data using audio loop example

Hi @Dinakaran Palani​ ,

if you follow the datapath of the audio signal you will find the audio buffer.

once you find it, you can store it in a long array until you have enough samples to make one second.

hope this helps,

Hi @niccolo.ruffini​ 

how frequently should I capture the data from pcm buffer to another buffer

the second one is how should I declare that buffer for storing one-second samples for the sampling rate 16000 for single-channel

if I declare an array of uint16_t[16000] if I do so I am getting excessive use of ram

Hi @Dinakaran Palani​ ,

you should capture data from the buffer every time it is full, otherwise you loose samples.

do you get the error even if you use the malloc?

Hi @Dinakaran Palani​ ,

you can follow this link to check how to use the malloc function.

i tried allocating by using the snippet as shown in the example link I am not able to allocate 16000 memory location

Hi @Dinakaran Palani​ ,

What system are you using?
