J2ME/Blackberry - get audio signal amplitude level?

Question

Hi! Is it possible in j2me to measure signal amplitude of audio record made by JSR-135 Player?
I know I can access buffer, but then what?

Target model Bold 9000, supported formats PCM and AMR. Which format I should use?

Thank you!

Answer 1

In most devices, only MID format with a single track is supported. That is the mid0 format that supports multiple instruments in one single track. I am not sure if the api provides the facility to measure the amplitude of a signal. To convert mid files to you can use Anvil Studio that has both free and pro versions

To record audio you need to use Manager.createPlayer("capture://audio"). Also leave the encoding (PCM or AMR) to the device implementation because some phones don't support PCM/AMR

Hope this helps!
