[LAU] [New music]: Kisses don't lie, a ballad

by Jeanette C.

Hey hey, the classification as ballad was probably unnecessary, with that title. Here it is and some (remarkable) remarks below: http://juliencoder.de/nama/kisses_dont_lie.ogg http://juliencoder.de/nama/kisses_dont_lie.mp3 This is only an instrumental, should you be female with a good strong voice and willing to give it a try: please get in touch. This piece actually came to me in a dream. Well, I dreamt its chorus. It was so strong in my mind when I awoke that I wanted to make it the perfect example of a powerful love ballad. The dream title had been "Chocolate don't lie", as sweet as that might be, I decided the kisses would make more sense. :) The rest of the song came easily, perhaps partly remembered from the dream, partly obvious (to me), seeing that I wanted to create my personal clichee or essence of that type of song. Technically this song uses Yoshimi, LinuxSampler with a self-compiled acoustic drumkit from parts of the Salamander kit, the AVLinux kit and one or two extras. Also in LinuxSampler a proprietary acoustic piano and SSO strings. This was further augmented by additional hardware synths of all kinds. The electric piano is the real DX7 full-tines on a DX7. :) Of course it needed tons of LADSPA and LV2 plugins, since everything was recorded completely dry. Fons Adriaensen's G2Verb, the TAP plate, Invada and Calf mixing tools and Fons' great four band parametric EQ. Guitars were played and recorded by Joy Bausch on a non-Linux platform. Very many thanks to him for such a wonderful and to-the-point interpretation of my intentions. If you have comments or feedback - particularlynice one :) -, please let me know. But also don't hesitate to give the other kind of comment. Best wishes and enjoy, Jeanette -------- * Website: http://juliencoder.de - for summer is a state of sound * SoundCloud: https://soundcloud.com/jeanette_c * Youtube: https://www.youtube.com/channel/UCMS4rfGrTwz8W7jhC1Jnv7g * GitHub: https://github.com/jeanette-c * Twitter: https://twitter.com/jeanette_c_s I'm so curious, what do you think of me <3 (Britney Spears)

Re: [LAU] Audio seamless switch

On Sun, June 17, 2018 3:16 am, Benny Alexandar wrote: > The user who is listening to it should not notice the switching, and this > switching happens when the quality of one audio is degraded compared to > other. Is like the digital radio schemes where a digital program and an analog FM signal are both broadcast, and if the reception changes such that the digital signal cannot be received the audio is switched to the analog signal? > Yes delay estimation is required as the delay is not known upfront. Is that acceptable to require user intervention, e.g. adjust delay until it sounds correct, or are you looking for automatic delay estimation? If you want automatic delay estimation it is unlikely you will find anything off the shelf that does what you want. You would need to check the auto-correlation value as a function of delay and find the delay at which the signals are most correlated. > In addition to re-sampling stretching also required. You have not adequately explained why either resampling or stretching would be required. If the two streams are from the same source but one path has a delay, then presumably a fixed delay would be all you need. -- Chris Caudle

[LAU] xoscope and the jack ALSA plugin

by Dominique Michel

Hi all, With xoscope, each time I add a trace, it disconnect its input ports and reconnect to some default. The strange thing is than it seam to be ALSA that do that. I startx xoscope with its default input connection, which is ALSA default. As jack is running all the time, I defined ALSA default to use the jack ALSA plugin in my asoundrc: pcm.rawjack { type jack playback_ports { 0 system:playback_1 1 system:playback_2 } capture_ports { 0 system:capture_1 1 system:capture_2 } } pcm.jack { type plug slave { pcm "rawjack" } hint { description "JACK Audio Connection Kit" } } pcm.!default { type plug slave { pcm "rawjack" } } ctl.!default { type plug slave { pcm "rawjack" } } pcm.dsp { type plug slave { pcm "rawjack" } } pcm.dsp0 { type plug slave { pcm "rawjack" } } pcm.dsp1 { type plug slave { pcm "rawjack" } } # for ameter: pcm_scope.ameter { type ameter } pcm_scope_type.ameter { lib /usr/lib64/libameter.so.0.0.0 } pcm.ameter { type meter slave.pcm 'hw:4,0' # can be hw or hw:0,1 etc... scopes.0 ameter } pcm.dsp4 ameter ## At startup, xoscope get connected to system:playback_1 and system:playback_2 If I disconnect it and reconnect it to some other audio source using catia, xoscope wotk fine, but as soon I do various operations including adding a trace, it disconnect and reconnect as explained. Is it something I can do to avoid that and get xoscope to stay connected as I connect it with catia? Cheers, Dominique -- If you have a problem and you are not doing anything to fix it, you are at the heart of the problem.

[LAU] [OT] Podcast recommending synth-based (pop)music

by Jeanette C.

Hey hey, I know this is off-topic, but from remarks made by several members over time, I gather that quite a few people here enjoy music beyond the mainstream. The offerings are so generous these days that it can be very hard finding one's own new music. So I'm looking for a podcast or youtube-show recommending new synth-based music. So what am I looking for? I'm looking for something focused on songs, closed units of three to ten minutes, with or without vocals, hopefully nice independent sound design. I'm looking for melodic and/or harmonic. So not your average modular-synth stuff nor typically highly experimental sound art, as our community would see it - from time to time - from Csound and similar. Neither am I looking for no-dynamics-at-all dance music. I like that too, but it's easy to find. :) If I were to mention artists, I could only think of Imogen Heap and this rather obscure piece by Rod Morris, who himself appears to be a little obscure: youtu.be/tJr_LXxxOVI On the long'ish side, but it has interesting sounds and a strong atmosphere. Any recommendations? Perhaps genre names to particularly take into account? Or other search directions/starting points? I have tried but failed so far. Best wishes and sorry for the OT, Jeanette -------- * Website: http://juliencoder.de - for summer is a state of sound * SoundCloud: https://soundcloud.com/jeanette_c * Youtube: https://www.youtube.com/channel/UCMS4rfGrTwz8W7jhC1Jnv7g * GitHub: https://github.com/jeanette-c * Twitter: https://twitter.com/jeanette_c_s You should take me as I am 'Cause I can promise you Baby, what you see is what ytou get <3 (Britney Spears)

[LAU] Is -Xalsarawidi the same as -Xraw or -Xseq?

by Victor A. Stoichita

Hi, I’ve read in various places (like here [1]) about an option to jack2 named -Xalsarawmidi. The man page of my jackdmp 1.9.12 documents only "raw" and "seq". Is alsarawmidi an alias for one of these? Regards, Victor [1]http://jack-audio.10948.n7.nabble.com/Jack-Devel-a2jmidi-and-jack-tp19285…

[LAU] Yoshimi and Midish issue (no notes played)

by Jeanette C.

Hey hey, I have an issue - again with Yoshimi and the commandline MIDI sequencer Midish. Yoshimi will not receive any notes from Midish, though the connection is made, as seen by a message on the Yoshimi commandline. Midish uses the ALSA Sequencer API, but only offers the port when it is running. Midish does work fine with LinuxSampler, hardware and setBfree. I don't know which of the two, Yoshimi or Midish, does something special to prevent them from working together. Will, if you'd like to test it, I have seen the midish is available as a package in Debian and Ubuntu. On Arch it is in AUR. Here's the simplest test: bash prompt # rmidish [within midish] dnew 0 "name of your keyboard under aconnect -li" ro dnew 1 "yoshimi" wo inew keyboard {0 0} onew yosh {1 0} tnew test_track fnew test_filt fmap {any keyboard} {any yosh} tsetf test_filt r [play notes on your keyboard] s [stops recording] p [should play the notes back] s exit [press enter twice, if Midish doesn't quit immediately] Sorry, it's a long list of commands, but you should be able to copy them verbatim, except for the alsa SEQ name of your input device. Any idea what might be happening? I can see the connects and disconnects, but nothing more.
