So is there something good about this? Is it useful only when I sample at 48 khz and keep the file at 48 khz? In this case how will sound my 48 khz wave file on a machine with a 44 khz sound card? Thanks in advance for responding.

Hi all! I hope this is the correct list for fluidsynth problems. Meanwhile I use fluidsynth as a software MIDI synthsizer. and it works very well (especially because my new PC has 1 GByte RAM, thus I can use the Fluid - Release 3 soundfont from http://www.hammersound.net/) But there are 2 problems concerning strings (program number 48 in GM scale with all SF2 soundfonts) and clarinet (program number 71 in GM scale, with soundfont 8mbgmsfx.sf2). It seems fluidsynth does not correctly handle the sustain level. Please have a look at: http://rnvs.informatik.tu-chemnitz.de/FLUID/fluidtest.html There you can find a 4 measure MIDI file "exam_strings.mid" of strings playing whole notes. If I use the Fluid - Release 3 soundfont (or any other SF2-GM-soundfont) with Audigy 2- (or AWE 64-) wavtable synthesizer I hear what I expect: The strings hold the tone over the whole measure. If I play the same MIDI file with fluidsynth I hear a short attack and then the volume decreases for sustain to a very low almost inaudible level. Thus, the srings play some kind of stacatto. The same holds for the clarinet, but only if I use soundfont 8mbgmsfx.sf2. Interestingly this effect does not occur in case of choir "Ahhh" . You'll find example exam_choirA.mid at the same page. Perhaps the 2 examples can help to clariyfy what the problem is. I use fluidsynth version 1.0.3 -- J.Anders, Chemnitz, GERMANY (ja(a)informatik.tu-chemnitz.de)

And the volume difference between attack and sustain is much too big. Again: It concerns only the srings of all soundfonts. And the clarinet of some soundfonts. Perhaps the SF2 format has still a special statement which orrcurs very seldom and which is ignored by fluidsynth.(?) -- J.Anders, Chemnitz, GERMANY (ja(a)informatik.tu-chemnitz.de)

This didn't help but I changend in line 1362 after: case GEN_VOLENVHOLD: /* SF2.01 section 8.1.3 # 35 */ case GEN_KEYTOVOLENVHOLD: /* SF2.01 section 8.1.3 # 39 */ count = calculate_hold_decay_buffers(voice, GEN_VOLENVHOLD, GEN_KEYTOVOLENVHOLD, 0); /* 0 means: hold */ if (count < 98) count = 1771; ^^^^^ Now the strings hold the tone but there is a small problem in release. I assume I could fix this similary. But more interesting is: I printed out the "count" values at GEN_VOLENVHOLD GEN_VOLENVDECAY (GEN_VOLENVSUSTAIN, GEN_KEYTOVOLENVDECAY) GEN_MODENVRELEASE If I play the strings (program number 48 in GM scale) the values are: GEN_MODENVRELEASE: 1191 GEN_VOLENVHOLD: 1771 GEN_VOLENVDECAY: 1771 If I do the same wit choir A (program number 52 in GM scale) the values are: GEN_MODENVRELEASE: 728 GEN_VOLENVHOLD: 792 GEN_VOLENVDECAY: 19464 The difference is surprising because the strings and the choirA have certainly a similar envelope. Therefore I changed again at: case GEN_VOLENVHOLD: /* SF2.01 section 8.1.3 # 35 */ case GEN_KEYTOVOLENVHOLD: count = calculate_hold_decay_buffers(voice, GEN_VOLENVHOLD, GEN_KEYTOVOLENVHOLD, 0); /* 0 means: hold */ if (count < 98) count = 19464; ^^^^^ and at: case GEN_VOLENVDECAY: /* SF2.01 section 8.1.3 # 36 */ case GEN_VOLENVSUSTAIN: /* SF2.01 section 8.1.3 # 37 */ case GEN_KEYTOVOLENVDECAY: /* SF2.01 section 8.1.3 # 40 */ count = calculate_hold_decay_buffers(voice, GEN_VOLENVDECAY, GEN_KEYTOVOLENVDECAY, 1); /* 1 for decay */ if (count < 2000) count = 19464; ^^^^ ^^^^^ ... and the strings are still too quietly but if I increase the volume of the single NOTE_ON commands the strings sound (almost) like on hardware wavetable synthesizer (with small distortions). Because of the great differences (1771 << 19464) I assume still a SF2 interpretation error. Feel free to give me instructions about what else shall I test. -- J.Anders, Chemnitz, GERMANY (ja(a)informatik.tu-chemnitz.de)

That was true until now, although I believe the latest PortAudio supports JACK and a version of Audacity incorporating this is well under way. Personally, I like to be able to undo effects because I frequently get them wrong! There is a LADPSA effects preview in version 1.20-pre1, which helps. But for real-time effects work, would an in-memory rather than disk-based application be better? Cheers Daniel

(Probably with the exception of sound editors I, since they are most oftenly, by definition, changing the actual data) Some examples: -Ardour -MusE -Rosegarden -Ecasound - a bunch of helper apps, like jack-rack (modular synths like) - Alsa Modular Synth - Spiral Synth Modular - gAlan and many others that I've forgotten /Robert
