    Tips and tricks

    I thought I’d share some thoughts here some might find helpful: If your Dac has an adjustable output voltage (my Motu has a trim that varies output from -4 to + 20 dBu), you should adjust it to match your amp’s input sensitivity. Too low and you won’t get as loud as you could, or conversely too...

    Starting over. What do I need to get(or purchase) to make Audiolense work for 7.2.4

    Does this AVR model meet your needs? https://www.denon.com/en-us/product/av-receivers/avr-x4700h It seems to be a 9.2 ch, HDMI 2.1, Auro-3d upmixing AVR and available on Denon's website $2,000.

    Isn't HDMI 2.1 already available ? https://www.primecables.ca/p-373528-cab-pc-07938-3ft-hdmi-21-cable-8k-120hz-ultra-high-speed-48gbps-4320p-uhd-hdr-24awg-braided-hdmi-cord-primecables

    It sounds like your computer security is getting in the way. If you disable the web security monitoring and/or firewall, you might manage to download the file. In the meantime, you can still try configuring your windows audio output to 7.2.4 (or the closest you can get to that), and playing...

    Hi Richard, On my PC, Audiolense is able to do sweeps in 5.1 through the HDMI cable. There are two tricks, the first is to use Directsound or Windows MME (for exampe in my case "marantz-AVR (Intel(R Display A (Windows MME))") as a driver rather than ASIO4All or WASAPI. The second thing is in...

    Av show

    Hi Bernt Maybe you already know about this online expo, but I just found out about it on audio science review and thought it might be a good way to bring your product to a wider audience, if you have the time and interest...

    Feature request

    Hi Bernt, It would be great if there was a way to save the settings associated with a filter. We could then go back to an old filter and change it a bit. It would also allow us to easily exchange our settings with one another on the forum and learn from each other. When you save a filter, if a...

    8ch dac for AL and Roon?

    In the example of a preamp with -100dB SNR, the noise floor is at -100dB, fixed, regardless of the signal amplitude. If you play a full volume signal, the ratio of signal to noise is 100dB. If you turn the volume down, the signal is reduced by say 30dB. The noise floor does not go down with it...

    8ch dac for AL and Roon?

    I’m not sure I understood your question. can you explain a bit more? I think he’s saying that Roon has a lower noise floor than a pre-amp (esp with a 24bit signal), but that in the end it’s irrelevant since an amp’s noise floor is high enough that unless you listen full blast the dynamic range...

    8ch dac for AL and Roon?

    Just a small correction. When I talked about my MOTU DAC I said I use Roon's DSP volume which is 'not ideal'. I stand corrected. It turns out Roon's DSP volume control is apparently better than a harde wired volume control: https://community.roonlabs.com/t/better-volume-control/126279/13...

    8ch dac for AL and Roon?

    my roon runs on a nuc pc (fanless), connected via usb to the motu.

    8ch dac for AL and Roon?

    I use a Motu 8A. It works well but has 3 drawbacks: no volume control (you can use Roon's DSP volume control but it's not ideal), it loses the signal if you change the sample rate- you have to press play twice (I convert everything in Roon to 96kHz to avoid that), in my system it makes a pop...

    Convert correction file format

    Thank you Bernt.

    Convert correction file format

    I saved a filter in Roon format, but forgot to save it as ALC as well (BTW, it'd be awesome if one could select several formats at the same time, and have AL remember so it always save in all versions in one go). I can't remember what correction procedure settings I'd used, so reloading the...
