Tim and team – many thanks for developing and maintaining MoOde – there is usually at least one instance playing around the house somewhere – definitely time for another donation!
I’ve not gotten round to using DSP yet – I usually just get drawn into listening to the music and forget about fiddling with any of the settings, but I’m thinking about playing with the Camilla options now accessed via MoOde. I don’t use headphones at home, so my interest is around Speaker and Room Eq. I’ve started reading the very useful material provided by @bitlab – thanks! I’ve also accessed the links kindly provided by @DRONE7 and @jonners, and the Camilla materials directly on the DIY Audio threads and Github. My conclusion is that I have a steep learning curve ahead that will keep me occupied for a while…
I already have a few questions that maybe someone on the form has already covered and can point me in the right direction:
1. I’ll be using REW for room and speaker scans on the way to convolution files etc, but getting a suitable calibrated microphone at a reasonable price is close to impossible at the moment. I have an Audyssey ACM1HB microphone (they used to be supplied under various brands with home cinema amps to help with setup) - has anyone any experience of trying this – there are a few hits around t’interweb suggesting it can work reasonable well?
2. Does anyone know of a similar resource to the AutoEQ (headphones) page – but for speakers?
3. It seems that Convolution filters need to be created for each sample rate to be played. My music has a range of rates, and would pose a problem. I think there is a workaround in Camilla, but I don’t understand that yet. Would it be possible to set SOX to resample to a common rate and bit depth (e.g. 24/192) to avoid this constraint – i.e. does SOX do its stuff before passing it to Camilla?
4. Is there a recommended minimum RPi for this, especially if using something like 24/192 (and maybe resampling to get there)? (I won’t be running REW on the Pi).
(I’m not sure if this is the right thread – apologies if not).
Regards
Adrian
