If you used JAMIN, I'd love to see the actual *.jam files to see exactly what you did so I can learn from that. So, replying kind of to everyone: As for bass rolloff, I'm rolling off with Glame Highpass 4-pole filter at 38Hz right now. There ain't nothing below that. The kick is boosted by 1.5dB at 50Hz. The bass is boosted by similar amount at 60Hz. I'll play around with different values, also rolling off 80Hz on bass. The kick DOES have compression, SC4, from memory: 5ms, 4:1, 100ms release, and it grabs from 2dB to 8dB of gain reduction. Bass is just limited with a nice tube compressor at recording time; the bass player's fingers are their own compression (he's got an active preamp bass, and he plays loud). As for clips, I sure hope there aren't any on the guitar, and I'd be surprised if there were. What you're hearing on the sax is the "slap" of the reed he was using. I've got a compressor on that too. The snare is mic'ed top and bottom (phase adjusted in Ardour), and there's compression on both of those channels. I'll try messing around with 100Hz and figuring out what's in that range, also maybe notching it out. As for compression, I don't understand how it could solve the "car stereo problem". I am NOT hearing sudden peaks of energy on car stereos, I'm hearing just way too much kick, ALL the time, and also way too much bass, ALL the time. Come to think of it, I'm hearing way too much low mids all around on car stereos and club systems, even the guitar and vocals... starting to point towards that 100Hz area... perhaps I'll try hauling those out. Thanks everyone for the comments! -ken _______________________________________________ Linux-audio-user mailing list Linux-audio-user@xxxxxxxxxxxxxxxxxxxx http://lists.linuxaudio.org/listinfo/linux-audio-user
