Audio capture
Hi, i'm attempting to capture audio data from a targetdataline on a specific mixer unsuccessfully apparently.
I currently have:
Mixer.Info[] mixerInfo = AudioSystem.getMixerInfo();
And when printing all the info out of this, I have the following mixers:
Primary Sound Driver
SB X-Fi Audio [DC00]
Realtek AC97 Audio
Primary Sound Capture Driver
SB X-Fi Audio [DC00]
Realtek AC97 Audio
Java Sound Audio Engine
Port SB X-Fi Audio [DC00]
Port Realtek AC97 Audio
Of which I presume, I wish to be using one of the SB X-FI audio mixers, since thats my default sound output.
The problem i'm having however is that I cannot seem to capture any data from this line.
Mixer mixer = AudioSystem.
getMixer(mixerInfo[4]);
targetDataLine = (TargetDataLine)
mixer.getLine(dataLineInfo);
(Have tried other mixers with varying success as to whether they break due to unsupported format or not basically)
I then create a seperate thread to do the capturing into a temporary buffer but the buffer is just writing values of -1, 0, and 1 (which I put down to low level static signal on an input/output which is receiving no data IE isn't plugged into anything).
My SB X-Fi audio has several inputs and outputs (5 channel sound across 3 ports and 1 channel input).
All I want really is integer values for current sound playing (IE frequency values) so that I can create some cool visualisations out of the data.
