With Android 7, a device that supports PROPERTY_SUPPORT_AUDIO_SOURCE_UNPROCESSED, it must fulfill:
- Audio input sensitivity MUST be set such that a 1000 Hz sinusoidal tone source played at 94 dB Sound Pressure Level (SPL) yields a response with RMS of 520 for 16 bit-samples (or -36 dB Full Scale for floating point/double precision samples). This would imply that at 0 dB FS the SPL would be 130 dB, which is the equivalent of standing 1 meter behind a fighter jet while it takes off !!!!! Question: What was the reasoning behind the spec point above? Regards /Robert -- You received this message because you are subscribed to the Google Groups "Android Developers" group.
