[linux-audio-user] exporting fft data from snd

by Declan Grady

Hi, Using snd-6, can i export the fft data as an ascii file ? My goal is to compare two or more spectra, and I can't figure out how to do this within snd, so if I could export the data I could use gnuplot. Any suggestions ? Thanks, Declan

[linux-audio-user] Big professional tiMIDIty patchset.. Any interrest ?

by Roel de Wit

Hi, I am one of two persons in Utopia Sound Division, makers of profesionally sounding (and commercial) soundfonts since 1996.. I'm currently trying to find out if there would be any interrest in a commercial patchset which is natively developed for tiMIDIty. A few days ago Jaroslav Kysela (from the ALSA dev crew) suggested me to try on this mailinglist so that's what I'm trying right now. In the past we've made products for many soundcards (among which was a 100+ MB patchset for the GUS PnP which the Ultrasound Driver project got native support for) of which only a few where released under our name on our website. My name can be found somewhere in the ALSA documentation and I've convinced (incl. signing contracts etc.) Gravis in the past to release all Gravis UltraSound driver sources to the public to allow further driver development.. I'll telling this to avoid a flame after sending this email which might be considered as an advertisement of some and to show that not all of our interrests are purely commercially. This message is only meant to get an idea of the interrest in the project described in this email (which is currently vaporware). What we've planned is a patchset sounding very similar to our current Utopia Live! soundfonts currently available for the SB Live! and Audigy soundcards (for information and MP3s check our website to get an idea what I'm talking about.). Since I noticed that tiMIDIty is still widely used these days in the Linux community I thought it might be a good idea to build a GM/GS patchset for tiMIDIty from scrap. This would mean a full GM instrumental set with all GS percussion kits (except for the SFX kit which only takes up space and is seldom used these days). All samples will be 48 Khz 16 bit and the final patchset is likely to cross the 300 MB barrier. Since the Linux community likes getting things for free we are planning to release a lower quality version of the patchset to the public to download for free (should it the product ever pass the vaporware status), while the full quality set would cost around 15$ and will below 50 MB to download (using oggvorbis compression). All replies on this message and the questions below will only be used by me to determine whether or not there is a reason to start with this project. No one who replies will be added to a mailinglist or will be contacted in the future about this product unless he/she asks for it by sending an email to me (roel(a)utopiasd.com). My replies on this matter will only be directly to the mailinglist and will only go about this current topic as long as it could be considered 'active' (or until a moderator considers it closed). Basically my questions are: - If you are a MIDI enthusiast of any form are you interrested in such a product if it truly stands out. With interrested I mean, would you be willing to buy it it would be developed ? - If you are a MIDI enthusiast but are not willing to pay for a product like this, do you think others would be. - What do you dislike or like about current tiMIDIty patchsets ? - Is there some size which you consider the maximum size of a good sounding patchset ? - Any other suggestions where to ask for interrest in a project like this (e.g. regarding sequencers which use tiMIDIty etc..) ? - Would you be interrested in beta-testing this product if it ever is made (send a PM) ? ... and last but not least: - Can anybody tell me what is and what is not correctly supported currently in tiMIDIty regarding SF2 files (we are trying to decide between the .PAT and .SF2 format). I've done some tests which have not been too promising with the SF2 format but I'm still considering it since .PAT files only allow single layered (mono) instruments. I'd appreciate any comment on this email (either negative or positive).. I hope that I've not crossed any rules in this mailinglist (I've been very careful to avoid doing so) since I really need some feedback for MIDI enthusiasts in the Linux community to decide whether or not it has any use for use to develop such a product. --- Roel / Utopia Sound Division http://www.utopiasd.com

[linux-audio-user] Csound for Linux

by Art Moore

Hello. Is anyone using Csound for Linux. There seems to be an awful lot of different versions around, iCsound, several unofficial versions and then the "official version". What are people using? I'm building iCsound now, but being new to the Csound world, I wonder if I need to be starting with something else. If Csound isn't complete, what should I be using?

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

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.

[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
