There are tools on Windows to automate the transfer of tapes to MP3: the software can sense when the record is actually being played and it starts recording, can sense when the record has ended and it stops recording, it can even merge two sides of the same tape into the same file, etc. It does that, I guess, by monitoring the signal on the inputs. Of course, all this stuff can be done even without a specialized tool, but when you have a huge number of tapes to transfer, it's nice to get a little help from a specialized app like that. So, is there anything like that available for Linux? -- Florin Andrei http://florin.myip.org/

ladspavst (Re: searching for good guitareffects

You probably won't get it to work though. It just worked with the old vstserver which won't compile anymore. However, making the ladspavst ladspa plugin work with fst or dssi-vst shouldn't be much work, maybe an hour or something. I'm surprise no one has ported it the last 6 years.

Need simple help measuring frequencies

by robert lazarski

Hi all, I converted the bass track off a midi file to ogg, muting out all the other tracks via timidity. The purpose being I'm about to buy some monitor speakers and I'm deciding what low frequency range is acceptable. I tried audacity and analyze-->plot spectrum, but I can't get that to show me what the low end is doing (I'm sure I'm missing something simple). Anyways, here's a link. What frequency is that bass around? How can I measure that? http://braziloutsource.com/random/carnival_bass.ogg If curious, I'm looking at the m-audio bx8a. I live in a remote place where I can't just walk into a store and demo them, so I have to buy off the internet. Thanks! Robert

Resonance

by John Anderson

Hey y'all I'm looking for something like an array of bandpass filters with feedback, to simulate resonance in different sized spaces. Doesn't have to be particularly real-world-accurate. I've looked at a bunch of jack-friendly and LADSPA effects, and things like that. But none of them seem to be quite what I'm after. Seems like the best option is JMax, or pd, or something like that. But they seem like long steep learning curves. bye John

Re: [LAU] ArdourVST - Latency Management

by Sebastian Tschöpel

Hi, > I'm new to ardour and would like to know how you created this "channel > strip". I am accustomed to certain features already being part of each > channels/tracks strip, like eq, under Windows recording apps, but have > found this isn't the case with ardour. > Could you please explain how you did this, thanks. Well, I don't know if we mean the same, but I just put the desired effects into the ardour-track in the mixer window. Nothing special. Check out this mixer strip: http://ardour.org/files/manual/images/mixerstrip.png The plugins "Barry's Sa....", "Allpass de..." and "AM pitcha..." are the plugins. And that is where you can load, unload, bypass, etc. the plugins. > Try inserting the "Artificial latency" plugin from the swh-plugins > mhmmm... that doesn't work. However, the latency of the swh plugin gets > compensated like it should be. > Those two statements contradict each other. What exactly is not working on it? How exactly are you using it? Hi. I did what Lars suggested, I tried inserting the "Artificial latency" plugin from the swh-plugins package after the VSTs. I understood "After the VSTs..." as loading it into the same channel strip right after the VST plugins. The channel routing is now: Audio -> Stereo Bus -> VST plugins -> swh artificial intelligence -> Ardour Fader/Panning ... -> Master Out. Then I tried to change the delay value of the swh plugin. The Swh plugin itself doesn't produce any effect. The VSTs are still delaying the channel without getting compensated. Am I doing something wrong? Thanks in advance. Best, Sebastian.

Trinity burn

by Joshua Boyd

http://createdigitalmusic.com/2008/01/08/ces-free-transmission-audio-distro… It is nice to see this coming along. Meanwhile, does anyone know anything about the Burn program on this? I'm curious to know more about if it has anything special to it, particularly in the way of integration with the various DAW programs.
