EDIT: after purchasing a new audio interface to replace my older M-Audio device that dies, I am no longer getting the results posted below. The frequency response I'm getting with the One X is now nearly identical to what GSMArena measured for the One S, which was excellent.
Please see my later post with a new graph.
I've posted this on XDA but decided to post here as well.
For those of you who are interested, I used RMAA and my M-Audio Firewire 410 audio interface to record and analyze the following:
- Samsung Nexus S with Voodoo Sound
- HTC One X LTE with sound processing off
- HTC One X LTE with Beats audio on (headphone set to Other)
I used supercurio's new app that plays a RMAA test signal to do this. Also, I repeated each test twice to verify that my results were accurate.
Note that on the One X, the output level doesn't go beyond -10dB when volume is at maximum, so I adjusted the Nexus S to -10 dB, even though it can go higher.
I have no idea if my methodology is sound, but I'd say the frequency response speaks for itself.
