NEW: Additional DSP Features

<< < (2/7) > >>

Bentley:
Have been hoping for and suggesting for this functionality for years!!  I'd like to have the ability to fine tune EQ values for different albums/tracks and have MC remember and re-apply the values each time I listen. Game changer!!!

+1 to the icing on the cake.

"Track specific DSP configuration is now unloaded when the track finishes" - This doesn't work properly for me. The DSP configuration for the next track in the playlist is loaded about 5 seconds before the end of the current track. This causes the end of the track to be played with no DSP configuration or the wrong one. It also causes a loud pop and break in the audio as it loads the DSP configuration for the next track (even if the DSP configuration is the same for both tracks). How can I make it use the DSP configuration to the end of the track?

I have also found it causes MC to crash regularly when double-clicking a track with a DSP configuration while another track is still playing or manually skipping around in a track with a DSP configuration by clicking the progress bar.

Just playing around with the new biquad feature I created an eq-filter in REW (via "Save filter coefficients to file") that internaly looks like this:
---------------------------------------------------------------
biquad1,
b0=0.9943567038075235,
b1=-1.6327458324854636,
b2=0.8909757879999204,
a1=1.6327458324854636,
a2=-0.8853324918074439,
biquad2,
b0=1.0328284933817395,

This filter loaded into DSP-Studio -> PEQ to my ears sounds equal or better than the equivalent filter settings that I used to enter by hand:

So far so good. My questions to the specialists here in this forum:

1) Is this a valid approach to use this feature?
2) Is there a maximum number of biquads to use?
3) I found no way to specify a channel (left/right) so I averaged R+L  measurements in REW and created the filter for this

Best regards and thanks in advance for any words of wisdom
