the MOTO Q just released by Verizon. I've been working speech and
media audio on Smartphones for a while now. Unlike speech there seems
to be no industry recognized MOS or objective testing tools to validate
media file record/playback minimum system performance. The defacto
benchmark product is the iPod. Other than Compression/ Codec scores,
what tests are done on a new iPod type portable players to assure
consumer audio quality. I'm running into testing issues such as Stereo
Bluetooth accessories & OS Embedded audio DSP width/EQ enhancement.
Besides traditional linearity metrics what tests would you add for
Smartphone based audio players?
