Make sure your mic is correctly selected as the input source. Next, right click on the newly created audio source and select Properties. Right click on the Sources and select Add -> Audio Input Capture. You don't need to configure any account info after installing, just skip it for now. OBS so far is the easiest and best way I have found to build and copy ReaFir data, plus it's free. We are assuming you have everything all set from that post, so if you don't, go back to our post on reducing noise with EQ APO. This is a continuation from our earlier post, how to reduce noise with EQ APO and Reafir. So long as you don't change mics, recording location, or hardware you really only need to do this once and re-do it when you make major changes. However, you CAN build one in OBS and import it into EQ APO. You can't actually build a noise profile automatically in EQ APO. i'd like to have a convolution filter for each channel if possible.The title of this post is a BIT misleading. That said, could you walk me through how i would achieve replacing my EQ section with a rePhase convolution filtering? i used DRC designer, but that wanted me to have impulse responses for LR in stereo. Then the rest of the includes are essentially the channel mapping back to the outputs, and since i have no dedicated SUB channel, the SUB output is added to each of the LCR low channels at a -4dB*SUB+Low reason for this was when i did each speaker independently, the sound just lost all of it's dynamics. Level match with pink noise to each channel independently, -20db signal, with -10 volume output calibrated to 72db on all channels (levels.txt)Įq <- this is where i'd love to use the filters, but for now i took the LCR highs measured together, did an auto eq in REW and use a single filter for LCR highs. Subsonic LR4 17hz on the subs (subsonic.txt)ĭelays on each channel with some basic math as a starting point then using the generated sign wave at crossover freq to adjust in REW with RTA for highest output (delays.txt) LR4 for a 250hz split between LCR highs (fusion8) and LCR lows (magnum12s) (crossover.txt) EAPO with a miniDSP UDAC8 which is a usb DAC converter giving me 8 RCA outputs at 2vRMSĭenon 2310: has multi-in, use to power LCR (diysg fusion8) and SUR L+R (volt 6s)ĭiy icepower amp: have 3 magnum12 woofers in a custom 2.5cuFt tuned to 24hz that are powered off thisĮAPO pushes all channels to virtual channels for processing (split.txt) Htpc: win7, plex for 90% of stuff watched. I have a rather unique setup compared to most Hey! so i've been a lurker here for some time, and too have found sanctuary in REW/EAPO but have had minimal success pulling off convolution successfully. I'm starting this thread to see what kinds of projects you all have going on using any of these amazing tools. One of the best things about Equalizer APO's convolver is that it's suprisingly low latency. Rephase allows you to correct phase blind by inputting the crossover topology. This system is superior to a lot of pro tools like Diraclive because for one thing, dirac live is practically useless for phase correction because you can only get accurate phase data at close range with lower volume levels. You can repeat that enough times to make your frequency response look unbelievably smooth. You can then remeasure that channel, create another filter to fine tune the response and load that into the next bank in rephase to make a more refined impulse file. Save the impulse as a mono WAV and select that as the convolution filter in Equalizer APO and WHAM you've got an active crossover, linear phase system. In rephase you can also correct the phase and set up crossovers for each channel. Then open rephase, import the measurement from REW and the filter settings. Then you can use REW to dial in the exact FR that you want and save those filter settings to a file. Using Equalizer APO, you can copy the L and R channel to other outputs on an 8 channel sound card. I would like to offer help to anyone who would like to learn how to make use of these tools because all of them are free and they can replace a lot of very expensive hardware. I've been working on calibrating audio systems for so long and now this combination is truly something special to me.
