| Could someone explain to me how this width example works? I have been trying to implement this using left/right delay but it does not sound as good as this: <CsoundSynthesizer> <CsOptions> </CsOptions> <CsInstruments> sr = 44100 kr = 4410 ksmps = 10 nchnls = 2 instr 1 ; Stereo Width Expander. ilevl = p4 ; Output level iwidth = p5 ; Stereo width: -1=Mono 0=Normal +1=Wide ifreq = p6 ; Bass cut frequency a1, a2 soundin "sa_beat1.aif" ahp1 atone a1, ifreq ahp2 atone a2, ifreq aout1 = (iwidth >= 0 ? a1 - ahp2*iwidth : a1 + a2*int(iwidth)) aout2 = (iwidth >= 0 ? a2 - ahp1*iwidth : a2 + a1*int(iwidth)) outs1 aout1*ilevl outs2 aout2*ilevl endin </CsInstruments> <CsScore> ; Strt Leng Levl Width Freq i01 0.00 1.50 1.00 -1.00 100 ; Mono i01 2.00 . . -0.50 . ; Narrow i01 4.00 . . 0.00 . ; Normal stereo i01 6.00 . . 0.50 . ; Wide i01 8.00 . . 1.00 . ; Very wide e </CsScore> </CsoundSynthesizer> |

| Hi, This is a typical Mid-Side image control (where you have a middle signal which is the sum and a side signal which is the subtraction, and you control the balance between both), but in this case, when trying to extend the width beyond the original, it uses a high-passed signal, so that phase cancellations don't occur in lower frequencies. Quite a nice idea that I hadn't come across before. Cheers, Andrés On Tue, Feb 21, 2012 at 2:47 AM, Roger Kelly <loraxman@gmail.com> wrote: Could someone explain to me how this width example works?
