[linux-audio-user] LADSPA plugins - warm sound quality

by Patrick Shirkey

Its partly a matter of taste - I like the hard digital filter sound, I think it makes a pleasant change from analogue filters warmth. In addition I'm a modular synthesist at heart, so if it annoyed me I would just bung a lowpass->valve sim->lowpass on the end (this is what most VST plugins will do). I think I tend to use, and think of LADSPA plugins at a lower level than most people. This became obvious at linuxtag. But, mostly, making plugins sound warm requires more work, and no-one has requested it (up til now). --------- Steve, since you wrote this I have been doing a lot more work with the ladpsa plugins and I tend to agree that the default sounds of a lot of them are very hard. Can you elaborate more on how and why you use "lowpass->valve sim->lowpass on the end" to create a more warm sound? Thanks. BTW. I think it would be a very good addition for the LAU FAQ so I'll add this as it comes to light. -- Patrick Shirkey - Boost Hardware Ltd.

[linux-audio-user] Audiotrak Inca 88 and Linux?

by Michael Kuhlmann

Hi all, I consider buying a Audiotrak Inca 88 Soundcard. I searched a bit around the net, but couldn't find any information if this card works with linux. Unfortunately i couldn't find any chipset info about this card. So my question is: Are there any linux drivers for this card.

[linux-audio-user] clicks and pops

by art moore

I'm using audacity and terminatorx in a couple of projects that I'm doing. Through the manipulation of sound, I get a fair amount of clicks and pops. (This is the nature of manipulated sounds, I realize that.) but does anyone know of a good declicker for Linux? It would speed up my process.

[linux-audio-user] Reply regarding our possible future tiMIDIty patchset.

by Roel de Wit

Hi, Since I receive this list in a 'Digest' format I'll reply to all questions (as far as they have not been replied by by others correctly) in one email. - Regarding from 'scrap vs scratch typo': Sorry my native language is not English and sometimes I make some mistakes sometimes. - Regarding: how this patchset would sound when comparing to Fluid (assuming it's played back under tiMIDIty): Fluid is a bank in SF2 format which was made to sound a true (realistic) as possible with all it's cons and pros. The main problem with 'realistic' patchsets is that it's hard to make all instruments fit together correctly. Next to often existing tuning problems they often just don't fit together. It's true that with some MIDIs it might some great but with others it might sound horrible or just lacking depth. All our past Utopia patchsets have been aiming at full sound and balance. This means (that whenever we do the job right) that 99.x% of the well sequenced MIDI files (in other words those who use the Roland Sound Canvas as a refference) will playback near perfectly. As a result of this our patchsets don't sound as realistic as a soundfont as Fluid might do but it will sound (near) perfectly balanced. Our previous products all have been in development since 1996 in some way when we made our Utopia Soundbank for the GUS PnP soundcards (check dejanews for some messages about that) from scratch (using .PAT files and a home-written editor to allow stereo voices) and thus no sample in it is used in any other soundbank/soundfont (legally). Ever since we've been fine-tuning and tweaking this base set of work we've done up till now.. So I'm pretty sure that the sound is unique and quite powerfull. To get an idea how this new patchset would sound like have a look on our website at http://www.utopiasd.com and listen to the Utopia Live! demonstration MP3s for the general idea and to the Acoustic Piano add-on v1.0 demonstration MP3s to get an idea how the piano that will be included in this new patchset will sound. Note that the Utopia Live! recordings are still from version 1.x and some instruments like the pianos are very outdated. Note that the current patchsets are limited to 31.5 MB (and more recently 35 MB but no MP3 recordings have been made of the later versions) and since size doesn't count too much with the tiMIDIty versions some instruments will sound much more realistic (at least that is the plan). Don't buy any of these products for use with tiMIDIty or another softsynth or hardware other than the SB Live!/Audigy claiming to be compatible with the soundfont format because it'll simply not work. - The final version of this patchset will be released in the form of a windows installer and a linux-perl installation script. So it should self install up to a point. To make the downloadable size acceptable everything will be compressed with the OggVorbis format. All samples will be 48 Khz 16 bit. My experience with Linux is still a bit limited (except for some private server maintenance) so the initial beta versions will only come in the form of a windows installer I fear. - To get an idea how the current patchsets are layered download the free 2 MB demo version of Utopia Live! and open it in Vienna (under windows or using an native SF2 editor under Linux). Note that the quality of these samples (and looppoints) are very bad due to use of extreme compression (it unpacks to about 36 MB). Still this should give you an idea how the layering is done in our products.. E.g. our Acoustic Piano add-on (no demo available) is in 48 Khz / 16 bit with 28 velocity layers. Layering use doesn't apply to tiMIDIty since we are currently not happy with SF2 results.. Some examples: Filters don't behave like they should, when playing a stereo voice you get a phasing effect when timing is critical, early note-cuttoffs etc.. I'll have a look at the tiMIDIty at sourceforge to see how things have improved and will take that into consideration when determining whether to use .PAT or SF2. If we use .PAT files make everything in Vienna in one use SF2 file and sample it from an Audigy 2 to create a (huge) single layer set of instruments. As a result, next to missing an stereo image the sound should be equal or better (bigger instruments) than our current Utopia patchsets. Regarding how they've been recorded or processed (e.g. our StereoID percussion) I won't give any details. I know the SF2 format by head but I don't know how tiMIDIty's implementation is. So far it seems terrible. - Regarding .PAT implementation.. I guess that tremelo/vibrato is correctly implemented ? From what I remember from back in 1997 it seemed to perform nearly perfectly when comparing to the GUS Classic. --- Roel / Utopia Sound Division http://www.utopiasd.com

I'd have thought the opposite arrangement (highish level out, lowish in) would introduce less noise.

[linux-audio-user] Which new digi-card for my linux box?

by Jackson Gibbs

Hey folks, I need to digitally transfer DAT's to my Linux box via a SPDIF coax cable. I'm wondering what the path of least resistance would be for getting this set up? I currently run Red Hat 8. I have a Zoltrix Nightengale Pro installed (which I understand is a CMedia 8738 chip?). I have put 3 hours of searching and tinkering into getting the Zoltrix card to work but haven't had any luck. So now I'm wondering whether there is another distro/card combination that will come closer to working out of the box? If not, does anyone have any advice for getting the Zoltrix card working? I'd sure appreciate any help. This is the last windoze task that I haven't been able to replicate on Linux. As soon as it can be accomplished I can format that WinXP drive and have more space for music ;-) -Jackson Gibbs

Re: [linux-audio-user] Koan/Generative music for Linux

by Gavin Stevens

(De-lurk mode) KeyKit is still going strong. Indeed it has been "software of the month" during November at the CNFractal Music Forum at Yahoo Groups. One other suggestion would be to try the Atari emulator XSteem. I understand that the latest version of XSteem has MIDI support. Sadly, I haven't had time to try it on my Linux box yet & have stuck with the Windows version "Steem". If you could get XSteem working, it would open up a whole universe of generative apps that were originally written for Atari ST. http://www.blimey.strayduck.com/index.htm is the Steem site.
