| Odd Impulse Response
First of all I'm a newbie so please bear with me.
Secondly I am only using REW to analyse results from another measurement/filter generation system, namely InguzAudio and DRC (I'm implementing room correction for a squeezebox based system).
I've imported the impulse respone generated by the InguzAudio app, and have the following questions:
1. The documentation for REW states that 32bit WAV impulse responses can be imported. I can only import as 16bit (which is OK as I have used Audacity to convery from 32bit-float). Is this a known feature?
2. My impulse response (in the %FS view) looks to be much as expected, although the graph tails off after just 50ms, rather than, say, 500ms in the documented examples. Should that concern me?
3. With db FS for the y axis, the impulse response looks very odd - a) the background nose seems quite high at -30db before the inital spike, and b) the shape continues to look odd afterwards.
The frequency response curve does however look OK, and the filters generated by DRC do make a positive change to the sound of my system. But in trying to use REW to better understand my system's behaviour I seem to be getting somewhat confused. Any help appreciated.
