Hello! I have a question about audio recording. I have developped android app that send audio data to other device real time. But, this app occur delay about 300ms when first send audio data.
Using Class AudioRecorder that supported by android.media.AudioRecord. Audio format is 8KHz frequency, MONO channel configuration and 16 bit PCM encording. For audio recording, get buffer size from AudioRecord.getMinBufferSize(...) is 4160bytes. So, after sent first audio data, App read and send audio data every 250ms~260ms. I guess reason of first 300ms delay because gather first audio data and for initialize AudioRecord. I tried using smaller buffer of AudioRecorder. URL : http://developer.android.com/reference/android/media/AudioRecord.html#AudioRecord(int, int, int, int, int) "Using values smaller than getMinBufferSize() will result in an initialization failure." YEEEEEE! initialization failure perfectly... Need way shorten the time for send data every 100ms. Plz, let me know good idea? -- You received this message because you are subscribed to the Google Groups "Android Developers" group.
