With all the talk about SIR lately, I'm wondering if anyone has compared it against Acoustic Mirror for performance, especially cpu usage? I know SIR is free, but other than that, is there a difference in function or quality?

Thanks,
JD

At the moment SIR only supports 16 bit impulse files (the next version should support 24 bit aswell). On the plus side, it's much lighter on cpu usage than Acoustic Mirror. If you haven't already tried SIR, then I suggest you give it a whirl , after all what have you got to lose?

Nothing to loose but all those mediocre verbs cluttering your hard drive .

i think the advantage of SIR against AM is the realtime use as a plugin in a sequencer and automate i.e. the tail length or the envelope. ( at least i can do in Oplat ) which is great fun with drums or weird fx.

ok then where can i find SIR?

You can find SIR here: http://www.knufinke.de/sir/

And you can find impulses here www.noisevault.com

Some of the impulses on that site are in 24 bit ( which as stated previously, is not supported by SIR ). So, I converted them to 16 bit, but I get an error when trying to load these 16 bits wavs into SIR. Anyone else have this problem?

Hmm, maybe you converted them to 16 bit mono or something . I didnt have any problems after converting them.

Hi,

I guess you used Wavelab to convert them. If so, you must go into Wavelab's Preferences and untick the File option Optimized File Header. This does the trick.

If not, make sure the sample rate is 44.1 kHz. Some of the impulses at Noisevault are 48 kHz.

All the best,

Magnus

Is SIR a VST?

Yes.
