You can get really good USB mixers for less than you paid for those cards.

If your going to analyse reverb and effect then you need a card with multiple 
channels as any analysis will fall foul of clock drift on multi card setups.

I like alan just use good quality electrets on a preamp but spunds like 
something more professional and robust might be needed.

I suggest you look at the prosumer home recording with a google for ‘multi 
channel usb mic mixer’

Read a couple of reviews.

Latency is pretty easy to find as play spaced ‘tick’ from the output and record 
and load up in audacity to get a accurate latency.

For a single pcie card Creative Sound Blaster Z High Performance Gaming Sound 
Card < $80 and also include a really good beamforming microphone.

Depends what you want to analyse if room impulse is a thing then you want 
several mics on several channels with something like the 4 channel prob being 
what you need.
Creative is more of a gaming thing but prob cheapest single with mic that is 
really good quality and you will know the mic is matched to the hardware and 
has a dsp app that may be something that will of much interest.

I'm not sure about the latency since I can't even measure it but I'd
go to USB.  Being tied to a PCI(e) slot is an awful nuisance these
days.  Many machines have multiple USB busses, try putting the sound
card on a bus without much else if there's a problem.  I'm not sure if
your application is closer to a language lab or speech recognition.

Startech is generally a good company, you can also get these cheaper
and faster through Amazon.

I also have a few Chinese clones bought through Aliexpress that seem
to work fine for general playback and recording.

Preamps aren't just gain but supply operating power to electret
microphones.  I do amateur nature recordings with home-built 4
transistor preamps and generic electret capsules, maybe $5 parts cost
total.

[Alsa-user] Suitable replacement card for Xonar PCI(e) cards

2021-06-14 Thread Maarten Duijndam via Alsa-user

Dear alsa users,

We are looking for a replacement card for PCI(e) audio that we are using 
in our linguistics laboratory. We have been quite happy with the older 
ASUS Xonar D2 pci and ASUS Essence STX II PCIe cards. Unfortunately, 
these are out of stock in the Netherlands, I don't know whether they are 
still being made. We need quite a number of those devices in roughly 
15-25 pc's in our labs. So they were good value for money at roughly 200 
euro or dollars each. The xonars worked out of the box on recent 
versions of Ubuntu and this great to have so we do not have to make 
small adjustments to the all pc's in the lab.


Some background on psychology/linguistics research. We are looking for a 
sound card that is easy to use, and without many "expert" features. For 
quality speech recordings we are looking for devices that has a high 
signal to noise ratio (in practice we used an analog mic preamp and put 
the preamps output in the line out of the preamp in the line in of the 
xonar cards). Also we like to record as naturally as possible and we 
don't value Digital signal processors (DSPs) that mimics special preamps.
Additionally, cards using DSPs might have an internal buffer in which 
they do there processing and take additional latency. In artificial 
grammar learning or other types of experiments in which speech stimuli 
are presented to participant in our lab we greatly value the timing of 
the presentation of those speech stimuli. That is: we try to schedule a 
stimulus (speech or another sound) with 1ms accuracy. So If we know that 
ALSA or another backend uses a eg. 20ms playback/software buffer, we 
schedule the stimulus 20 ms ahead of time. We would like to keep any 
buffering delays as short as reasonably possible.


So coming back to the original question, the Xonars we were working with 
ran fine in for example Ubuntu-18.04 and even some older distributions. 
We would like to find a nice replacement that meets the requirements of 
a linguistics lab and are relatively easy to maintain. I don't know if 
this is the right place to ask, but I hope to get some input for we have 
tried quite a number of PCI(e)  devices from expensive RME equipment to 
cheaper Creative Sound BlasterX AE-5 Plus or very cheap TERRATEC Aureon 
devices. Perhaps we should move to USB class 1 and/or 2 compliant devices.


Hopefully some of you have experience with such equipment and is willing 
to give us a nice suggestion.


Best regards and thank you for your time,

Maarten
