mconvolution much lower volume when use 88.2 khz recordet impulse on 44.1 khz play rate

as normalize i have set adjust level . overall signal (100% wet) on 44.1 khz is more than 6 db reduce. only on 88.2 khz volume is correct
when i switch to adjust loudness then level problem go away but signal sound very dull too. maybe on convolution reverb can set oversampling ?. I have 6 cores and cpu benchmark for convolution show 0.36% for single CPU at 44.1 khz and 0.73% at 88.1 khz. I think upsample and downsample from 88 khz to 44 khz can not so dull and boost mid.

I'm afraid I don't really understand, a testing project? or a video maybe?

you can easy test. switch daw to 88 khz. then record in mconvolution with record and testtone a impulse. now switch DAW to 44khz. the recordet impulse sound diffrent. let me know if i should do a video.

Aaaha, you are recording just an impulse, then it's quite expected. The impulse will be generated in a higher sampling rate, so downsampled it becomes lower in energy. Impulses are weird

if transpose of impulse not work, maybe there can add upsampling feature mfreeformeq have. when i have only a 88 khz impulse i can then switch mconvolution to upsampling 2 and it sound correct with 88 khz impulse when DAW run at 44 khz ?

I don't follow, please tell me exactly what you are trying to achieve and how.

please see screenshot. when it is possible to switch mconvolution to 2* then 88 khz impulses can sound correct.MeldaProduction wrote: Sun Apr 11, 2021 6:44 pm I don't follow, please tell me exactly what you are trying to achieve and how.
