IMX28 gstreamer equalizer performance

Hi,

I am writing a app using gstreamer 0.10.35 on the IMX28 eval kit for audio playback only. The following command to play a .wav file works fine.

# gst-launch filesrc location=test.wav ! decodebin ! alsasink

If I try adding the equalizer-10bands plugin into the pipeline then audio playback starts to stutter badly and CPU usage jumps to 100%.

# gst-launch filesrc location=test.wav ! decodebin ! equalizer-10bands band0=1.0 ! alsasink

The 3 band equalizer is usable but still uses up a lot of CPU.

My question is there something I can do to improve the performance? Or is the IMX28 just not capable of doing software equalization?

Thanks!
