On my Tattoo there's a lot of stuttering and gui lag in ordinary use of ScanVox.
In logcat I see a lot of
W/AudioFlinger( 57): AudioRecordThread: buffer overflow
W/AudioFlinger( 57): AudioRecordThread: buffer overflow
W/AudioFlinger( 57): AudioRecordThread: buffer overflow
W/AudioFlinger( 57): AudioRecordThread: buffer overflow
In fact, the lag actually has the weird effect of shortening any audio that you put in -- presumably because of dropped buffers, the record buffer is slower to fill up than it should be so it plays back with a sped-up rhythm.
I tried with the default driver block size of 512 frames, also with 128 and with 2048, couldn't get the Tattoo to behave nicely.
