RE: [linux-audio-user] ... like an old vinyl

by Reuben Martin

First: Using an equalizer, kill all frequencies below ~600 and above ~2k. Use a graphic EQ for this. (The two values are just examples, you can play with both frequencies to get the desired sound you're looking for.) Second: get a recording of the inside blank track that comes after the last song of a noisy record. Loop this noise and mix it over top of the song once you've done the band pass filter from step one. -Reuben -----Original Message----- From: Michal Seta [mailto:mis@creazone.32k.org] Sent: Wednesday, October 22, 2003 8:32 PM To: A list for linux audio users Subject: [linux-audio-user] ... like an old vinyl Hi all, Does anyone know if it's possible, under linux, to turn a good quality audio recording into a file that sounds like an old vinyl record.

Those were pressed on shellac, not vinyl. The priciple's about the same, though - add a few random background ticks and clicks, a bit of white noise as many vinyl discs had tape noise from the master, possibly a bit of distortion on peaks if you want it to sound like a worn record/stylus, and also some gentle frequency variation at 0.5 Hz (for 33 1/3 rpm) to simulate a less-than perfect turntable or warped record. I'm sure it can be done with Linux tools... -- Anahata anahata(a)treewind.co.uk Tel: 01638 720444 http://www.treewind.co.uk Mob: 07976 263827 ------ I'd say its all possible with audacity: http://audacity.sourceforge.net Its an Multitrack-able Wave/Mp3/OGG-manipulation tool with LADSPA-support, I think. Anyway, there are a lot of "integrated plugins" that allows what you want to do. A real PROGRAMM can do what you want is not written, I think ... ;) Sascha Retzki _____________________________________________________________ Linux.Net -->Open Source to everyone Powered by Linare Corporation http://www.linare.com/

[linux-audio-user] Standalone LADSPA host?

by Adam King

Hi all, I was wondering if there is any application that can just act as a standalone LADSPA host - with a jack input/output that can be inserted into the signal chain. I've searched the net but couldn't find exactly what I'm after. Does such an application exist - or are there any plans for one? Cheers.

If I understand ALSA correctly, this is because it is the default device -hw:0. I think you would need to explicitly tell ALSA to use a different device. Have you read up on .asoundrc files? (I haven't (I know I ought to) - but I think it might be the answer). > If I set jack to Playback via the card with index 1 , so my ESS-Solo1 (snd-es1938): > # jackd -d alsa -d hw:0 -P hw:1 Why do you say "-d hw:0" if you want it to use hw:1? Try this: jackd -d alsa -d hw:1 Good luck :) |) |)enji ----- LOL, hi ! I see that it is "irresponsible" to post a msg begins with 'you know iam the guy xy, I had x problem' ... . Well: I have had several problems with my ESS-Solo1 soundcard to start various sound apps which using jack ... . The second card, the Es1371, IS able to start jack, the esssolo1 quits with some alsa-error msgs. I first thought the esssolo1-problem is a symbol-problem in the alsa-modules, but a recompilation ( a successfull ) did not change something with the "support" of the esssolo1 with jack. So my Ess-Solo1 cannot be used via jack. My second card, Es1371, can , but it is physically broken. just the output-port, so this little "whole" where I put the speakers in, you understand ? I want to pipe jack-output to my first card, the Ess-Solo1. So I want to use my Es1371 for my MiDI-keyboard, for capturing AND for STARTING various soundapps like muse,ardour and Rosegarden4 and so on, but let the Ess-Solo1 output all the stuff jackd gets. (*puh* ) So, my cards are NOW: Ess-solo1 <-> hw:0 Es1371 <-> hw:1 # jackd -d alsa -d hw:1 -P hw:0 Should set jack to USE the hw:1, so Es1371 and output via hw:0, my Ess-Solo1, right ? I think thats the question of my originally mail ;) . Sry, but I exchanged the order of both cards, I think in my first mail Ess-solo1 was hw:1 , but this is not good. You pointed it: My ess-solo1 is my normal sound-card for listening to music and so on, and it should be the first alsa card. So, the above command prints out the help-menue which u get via: # jackd -d alsa --help Why ? greetz, Sascha Retzki _____________________________________________________________ Linux.Net -->Open Source to everyone Powered by Linare Corporation http://www.linare.com/

[linux-audio-user] ALSA, jack and the other stuff: Two cards handling

by Sascha Retzki

Hi! I am the guy with the alsa problem you remember me ? Well, I recompiled alsa, this time without any unresolved symbols... . Don't work right, but I installed a second card from which I know that it worked well, but this card cannot output something ( the hardware-outport is broken [ ooups ] )... . This is my modules.conf: alias char-major-116 snd alias snd-card-0 snd-ens1371 alias snd-card-1 snd-es1938 alias char-major-14 soundcore alias sound-slot-0 snd-card-0 alias sound-slot-1 snd-card-1 # Es1371 #alias sound-service-0-0 snd-mixer-oss #alias sound-service-0-1 snd-seq-oss #alias sound-service-0-3 snd-pcm-oss #alias sound-service-0-8 snd-seq-oss #alias sound-service-0-12 snd-pcm-oss # ESS-Solo1 alias sound-service-1-0 snd-mixer-oss alias sound-service-1-1 snd-seq-oss alias sound-service-1-3 snd-pcm-oss alias sound-service-1-8 snd-seq-oss alias sound-service-1-12 snd-pcm-oss # options snd major=116 cards_limit=2 options snd-ens1371 index=0 options snd-es1938 index=1 ---- Everything seems to work fine, except that alsa uses my broken card, the ES1371 for audio output. If I set jack to Playback via the card with index 1 , so my ESS-Solo1 (snd-es1938): # jackd -d alsa -d hw:0 -P hw:1 Jack just prints out the helpscreen, and if you have a look by yourself: ... -P,--playback [name] playback output and optionally set the playback device (default: duplex) ... [name] can be "optionally set (to) the playback device", in my case hw:1, so my second card with card index 1, see modules.conf. Why this jack-error ? And any idea why sound-output is not piped by alsa generally ??

[linux-audio-user] vst plugins+instruments/cubase under linux

by luigi rensinghoff

Hi there ! I have a question concerning vst plugins/instruments under linux. I would like to use vst/plugins/instruments lets say absynth under linux and being controlled by pure data. I wonder if someone has tried a setup like that. Is it better to run vstserver or to run cubasesx under wine and within that the vst-plugins/instruments ??? Does someone have a cubasesx running under wine with vst instruments inside ??? How do i communicate with pd ?? Through midi-audio /JACK-connction ??? The howto i found http://www.djcj.org/LAU/quicktoots/toots/vst-plugins/ is a little bit too superficial (at least for me since i am not such a linux expert) , Is there anything more in depth - including all the steps for wine etc ??? Thanks in advance Luigi __________________________________ Do you Yahoo!? The New Yahoo! Shopping - with improved product search http://shopping.yahoo.com
