    Problem with Save Filter in AL 6.20

    I want to add to this thread after more testing. Starting with 192kHz sample rate measurement. I generated 2 sets of filter using the same parameters. I have maxed out the filter length to 128K. One for Roon, one for Audiolense Convolver. Using Roon, I have no problem at any sample rate. Using...

    Problem with Save Filter in AL 6.20

    Does it mean that ideally, I should do a measure at each sampling frequency and generate a filter for each measurement? For Roon zip file, I could combine the individual cfg and wav files. How about alc file?

    Problem with Save Filter in AL 6.20

    When saving filter, AL would ask you to choose the sample rate to support. I usually select the 6 that I used: 44.1, 48, 88.2, 96, 176.4, 192. I generate it in both alc and zip. My recent attempt seems to indicate that something is corrupted. When I playback at 176.4kHz/192kHz, something is out...

    Convolver streaming with different input and output USB devices

    Does the input and output device clock need to be synchronized in order for streaming to work properly?

    Convolver streaming with different input and output USB devices

    Can the Convolver support streaming with a USB input and a different USB output device? i.e. a USB ADC and a separate USB DAC.

    Audiolense Convolver with Roon

    Thanks for the reply. Separately, is there any audio performance difference between running the Audiolense Convolver vs the Roon DSP Convolver? Or pros and cons of using one vs the other?

    Audiolense Convolver with Roon

    I'm trying to use Roon with Audiolense Convolver, which I have already purchased a license. I have no issue with using Convolver with JRiver MC. When using Roon selecting Audiolense Convolver as an ASIO output device, the convolver reports with a red message "Process RAATServer Silent output/no...

    Remote volume control for AL convolver?

    I would vote for supporting standard USB HID volume control. This would allow any standard USB HID device that have volume control function to work with the app. This include standard USB keyboards that has multimedia control. (https://www.usb.org/sites/default/files/documents/hut1_12v2.pdf...

    Remote control for Audiolense Convolver

    I used VNC on iOS to remote into the desktop as control, but it is still a clunky solution. Remote desktop is similar. You still have to use mouse action (emulated on the touch screen) to control it, in addition to making sure that the volume control function is highlighted. What you want to...

    Remote control for Audiolense Convolver

    1) is there any remote control that can be integrated with the Convolver such that volume can be adjusted without using mouse+screen? 2) can the volume control increments (currently at 0.1dB) be adjusted to 0.5 or 1dB? Features request for Convolver: a) mute button b) polarity inversion

    Possible problem on Linear Phase vs Minimum Phase XO filter generation

    Change everything to minimum phase and no longer have the sample rate related problem, which doesn't really account for the previous issue that I ran into. If we use minimum phase target and minimum phase xover, that would mean that we wouldn't be able to achieve a zero phase speaker system. Is...

    Possible problem on Linear Phase vs Minimum Phase XO filter generation

    Hi Bernt, I have sent you the measurement file. If I understand correctly, whether the resample is done during filter creation, or resample the correction filter by the convolver on the fly, the result should be the same, as they are both processing the audio at the native/incoming sample rate...

    Possible problem on Linear Phase vs Minimum Phase XO filter generation

    I am setting up a 3-way 2-channel stereo setup using Audiolense XO. I have generated two sets of correction filters using the same measurement and target, one with the option "Minimum Phase Xover" checked, and one unchecked, which I presume implies linear phase. The simulated frequency responses...

    Convolver for streaming live input

    Tested the convolver and streaming seems to work. However, I ran into 2 problems: 1) It seems to like to start multiple instances by itself (i.e. 2 icons in menu bar). Starting MC27 seems to start the convolver automatically. If there is one instance open, it will open another one. Other than...

    Convolver for streaming live input

    You need to enable it on the device. Select USB mode and multichannel. The manual actually refer to it as a 6-ch in, 8-ch out device in multi-channel configuration. However, it only has 2-ch A/D and 4-ch D/A. The rest are digital channels (AES, SPDIF etc.). The following block diagram may help...
