Hi everybody!
What I'm trying to do is to manipulate a recorded audio file, in this
case to reverse it.
The temp file (.raw) I create during the recording works fine, but the
reversed one doesn't.
Pretty sure it's an easy task, I just can't find where the mistake
would be. Hope you can help..
Here's the code:
byte data[] = new byte[bufferSize];
byte rev_data[] = new byte[bufferSize];
String filename = getTempFilename();
String rev_filename= getTempRevFilename();
FileOutputStream os = null;
FileOutputStream os_rev = null;
try {
os = new FileOutputStream(filename);
} catch (FileNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
try {
os_rev = new FileOutputStream(rev_filename);
} catch (FileNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
int read = 0;
if(null != os){
while(isRecording){
read = recorder.read(data, 0,
bufferSize);
if(AudioRecord.ERROR_INVALID_OPERATION != read){
try {
os.write(data);
} catch (IOException e) {
e.printStackTrace();
}
}
}
for(int i=data.length-1, j=0;i>=0;i--,j++){
rev_data[j]=data[i];
}
try{
os_rev.write(rev_data);
} catch (IOException e) {
e.printStackTrace();
}
Thank you in advance!
