Thanks, I forgot SND. It's a very long time ago I use it. We have some problems with very strong digital distortions in some audiofiles after import them to Cubase and reload the project. The audiofiles are from ardour3 and I export them with the stem-export function. The wavefile is list with a tempo of 120,68 bpm in the in the pool from cubase, but I have recorded it with 84 bpm. I hop to find some more information in the header of the wavfile. .. chris 2013/10/24 Hartmut Noack <zettberlin(a)linuxuse.de> > Am 24.10.2013 09:52, schrieb Chris Bungue: > > Hi, looking for a possibility to view or edit the header of a wav file. > > SND can do that and anything else, one may want to do with any audiodata. > But it is quite a huge, weathered beast so expect some learning-curve. > > https://ccrma.stanford.edu/software/snd/ > > > > > any idea? > > > > Thanks > > Chris > > > > > > > > _______________________________________________ > > Linux-audio-user mailing list > > Linux-audio-user(a)lists.linuxaudio.org > > http://lists.linuxaudio.org/listinfo/linux-audio-user > > > >

[LAU] Lou Reed

by Ralf Mardorf

When I yesterday read that he died, I couldn't get rid of one of his songs. In my mined I heard one song again and again. It's a well known song, while I prefer songs of The Velvet Underground, yesterday none of those songs was in my mind, just that hit from him bothered me. This comes to mind by the the discussion about "I remember something my father said when I was very small. "If you *really* enjoy something, never do it as a job". He was right." To make a living out of something often is far away from the good emotions, ok, this is another thread. What song comes to your minds, when thinking of Lou Reed? I bet most will hear the same song as I did hear in my mind. Is the song you hear in your mind, the best song he performed?

[LAU] limiting email traffic

by Robin Gareus

Hi all, Due to excessive posts - in particular on the linux-audio-user email list, we are going to rate-limit the number of emails to 13 emails per user per 24 hours with direct follows-up replies to self counting twice. It is not unreasonable to assume that a single user posting more than 12 emails per day is either involved in a heated flame-war or otherwise disrupting reasonable discussion. Neither of which is acceptable on the LA email lists. We understand that some communication requires rapid exchange of many small snippets and recommend users who need to regularly post short messages many times per day to rather use services such as twitter, IRC or simply private email. The LA email lists are mainly intended for discussion, questions & answers, sharing and preservation of knowledge. Note that there are currently over 3000 persons subscribing to the LA lists, every single email sent to the list will result in 3000+ forwards and be archived in various places on the web. Offenders will be notified with a warning message with the 10th email within a day and after the 13th email temporarily banned for 6 hours from further posting to the given email list. Feel free to comment on this email here on this list, but official inquires should be addressed to members of the consortium. See http://linuxaudio.org/contact The system will be activated on 31/Oct/2013 if not vetoed. The actual rate-limit may also be adjusted over time to reflect list-behaviour. yours truly, robin

[LAU] OT: how do you follow your favorite artist's releases?

by Bearcat M. Şándor

Folks, I've been looking for a website that is not label specific that will notify me when a band or other performer releases new music. I would love it if i could go on to Amazon or discoggs or even lastfm, select Porcupine Tree, or Cat Jahnke or Meshuggah and say "send me an email when they come out with a new album." Aren't there feeds or anything to do this with? -- Bearcat M.

[LAU] new music--constructive criticism appreciated

by Rusty Perez

Hi folks! I'm working on a project. I'd like your constructive criticism on this track, just to make sure I'm headed in a good direction. https://dl.dropboxusercontent.com/u/30068518/DoTheyKnowItsChristmas_1.mp3 There will almost certainly be no retakes, but besides that, any commentary on eq or level or compression or effects or what ever would be appreciated. Or what's your over all impression? This will be the first time I've mixed an entire collection of music for myself so I'm a bit nervous and would like to get your take. Thanks! Rusty

[LAU] Examples of synth/drum live performance Jack setups ?

by Barney Holmes

Hello, I'm from a DJ'ing background and prefer to play live and record tracks by keeping everything as live as possible. Think of Richie Hawtin using locked groove drum loop records and this kind of thing to make a hybrid between DJ'ing and on-the-fly original track creation. I know Ardour and Jack. I can create totally presequenced productions but find that takes away my spontaneity. Are there examples out there of these kind of set ups ? I need as many examples as possible for encouragement if nothing else. I did start using Hydrogen to drive external drum synths, like Yoshimi that can make drum and percussion sounds, but the Hydrogen controls are set up for altering the included sample sets and don't do anything to the MIDI output. I suppose I'm trying to recreate the immediacy and spontaneity that using original hardware 808/909/sampler set ups used to be able to create. Another example was the immediate accessibility of Propellerhead Rebith 303. It has a good real time 303 implementation but all the percussion was sample based, which I want to move away from. I've found creating a drum in Yoshimi sounds *much* richer and more dynamic than samples. So what are you using out there ? Screen shots ? Peace djbarney

[LAU] [ANN] meters.lv2 v0.5.1

by Robin Gareus

Hi, In the wake of overhauling Ardour's bar-graph meters, I've taken the time to implement corresponding needle-style meters and more. meters.lv2 features 10 needle-style meters. Mono and stereo variants of DIN, Nordic, EBU, BBC and VU types (which are based on jmeters by Fons Adriaensen). Additionally it includes a Stereo Phase Correlation Meter (needle Display), an EBU-R128 Meter (also based on Fons' implementation) with Histogram and History display, a Digital True-Peak Meter (4x Oversampling, using zita-resampler), a Stereo Phase Scope (Goniometer) and a 31 Band Spectrum-Analyzer. Source-code, info and screenshots can be found at https://github.com/x42/meters.lv2 They have been tested in various environments and fine-tuned to match their corresponding real hardware type by Chris Goddard and Axel Müller. Currently the plugins come in Gtk2 (LV2 GtkUI) and openGL (LV2 #external-ui) variants. Both versions are installed in parallel. The main reason for this is portability and compatibility. Yet the GTK variant UI does run in the host's GUI-thread and may slow down UI response (in particular the goniometer). The openGL versions of the plugins do not have this issue, but require very recent versions of libcairo, libpixman and libpango which are thread-safe. Please see the README included with the source. Caveat: Note that the plugins use the LV2 idle-interface (lv2 >= 1.4.2) The plugin-host must to be compiled with 1.4.2 or a later version of the LV2 SDK. It also must support the http://lv2plug.in/ns/ext/resize-port/ extension. At the time of writing Ardour 3.4 and jalv.gtk from SVN >= 5129 do fulfill these criteria. as always, any feedback is welcome. robin

[LAU] Linuxaudio.org server admin

by Ivica Bukvic

Dear fellow linux audio/multimedia enthusiasts, It's been some time since I officially addressed the entire la* community. This has been in great part because things just worked. Robin, who has in great part been the mastermind behind a number of initiatives currently being hosted on the lao server has officially stepped down a year ago (even though I still tend to bug him way too often ;-) as the sys admin and while we have a couple additional volunteers helping man the server, it appears that we really need someone who will step in just like Robin did to help me carry the burden of maintaining this huge ecosystem of sites and pages. More so, it appears that some pages have been covered with spam/non-working content, and given the current state of lack of adequate manpower to manage these, my immediate response is to shut down ladspavst page which is currently in an awful state of disrepair, filled with non-working content and spam. The very fact it's taken me this long to spot it speaks to the fact that I alone cannot keep up with everything that is happening on the site. This is particularly important because if this gets any further out of hand, the University may decide that the content hosted on these pages goes against the very grain of what a taxpayer-run site should be hosting and we may lose what has been so far a very generous no-limits hosting. To put this in perspective, we've been burning steadily 1-2TB per month. For this reason, in the interest of our great multi-site ecosystem, I will be pulling down any sites that are not actively maintained and that also have submitable user content (read: ability to receive unfiltered spam). If anyone wishes to step up and maintain any of these, in order to avoid any further mishaps like the one with ladspavst, I would like to propose that from now on all the admins submit monthly blurbs assuring me that everything is indeed being managed as it should be. This will certainly help avoid situations like the one currently with ladspavst which is also not the first time we've had problems with that site. I can and will gladly bat for us to get us more hosting space and processing power, but this will be heavily contingent on ensuring that our site is not hosting anything that is potentially offensive or outright inappropriate. This does not mean that we should not have passionate discussions on our mailing lists, but at the same time I think one would be hard-pressed to convince anyone that links to questionable chemical substances or worse yet inappropriate content is something that will help us continue to enjoy this wonderful service. You all have been a part of this wonderful community and you all have in many ways helped shape it into something truly amazing. Let's make sure that we don't lose this in this process. My hope is that we will keep most (all?) sites intact. But the reality is that we simply currently do not have the adequate manpower to maintain all of it. More so, the server has had its instabilities that we're trying to address and on top of that soon we'll be forced to upgrade to a new KVM system as our University's infrastructure transitions to its new and better iteration. This transition will be by no means a small feat if we are to maintain an uninterrupted service and is something that will undoubtedly require your help. If anyone is interested and willing to assist in this process, please do not hesitate to contact me. Best wishes, ico

[LAU] new(ish?) open source source separation editor

by michael noble

Has anybody had a play with this? Looks, and more importantly, sounds like it works well enough to do some useful, creative, and/or obnoxious things. http://isse.sourceforge.net/
