Given all the chatroom talk about SIR, I'm surprised there's only 3 reviews here.
I've been a hardware based recorder for over 6 years, and went DAW about 4 months ago. Aside from all of the obvious reasons to switch, the #1 reason was to get 'that sound' especially on vocals. It had been a fairly frustrating few months, aside from the learning curve - I never really got close to 'that sound' until I found this plugin - I'm a convert now !

I was a little intimidated to try this program because of all the latency talk, but Tracktion 2 automatically compensates for it ! I left a 9 for 'stability', not because it has been 'unstable', but the latency and CPU draw (not quite as bad as I expected) can make using multiple plugins or an aux-buss applications a little taxing and tricky - there have been times I've wanted to use it, but went with a more basic reverb to avoid issues, but given the price - no complaints.

At any price, sonically this is a 10 and the free IR's online have covered every application I've needed thus far. I don't use it everytime I need reverb, but it's my go-to for most vocal applications and anytime an instrument is 'naked' in the mix - it can really fill a void without being overbearing.

Didn't want to bring an overall rating down so I left 10's but in reality - N/A's for documents and support - if they exist, I haven't needed them, and in the software world, I'm just a bit beyond novice. For newbies its not a plug-and-go, you need to download IR's and load them into the program to get different sounds(NA really for presets too, although the 2 available are pretty good).

The GUI gets a 10 too - there's nothing more that I've needed, and its been a breeze to navigate without a manual.

BOTTOM LINE - DOWLOAD THIS PLUGIN - its worth a try. Its the best one I have and ITS FREE !

Now, this may well be just me not being very knowable, but - how is "fixed latency" a feature? To me, it seems like a bug.

This appears to be no longer available. The link redirects to siraudiotools' products page, where you can buy SIR2. There is no entry for (free) SIR1.

@Thohi It's too slow to calculate convolution without latency. The only way to do it without latency is fully in the time domain, where each sample of output requires /n/ multiply-and-add operations (/n/ being the size of the convolution kernel). It's actually faster to FFT the input, multiply by the IR spectrum, and IFFT to get the output... but you have to collect an entire FFT frame's worth of audio before you can do that, hence the latency.

The link is now hidden... but remains available. It is this one:

How then do the other IR reverb plugins do it with little to no latency?
