Updated vocalremover.ny

David R. Sky — 2008-12-03T19:19:42

Hi, Attached is an updated version of vocalremover.ny. It has one additional input field "vocal reduction amount [percent]", default 100%. So if someone wants to have Agnetha and Anni-Frid as backup vocalists on an ABBA track they can reduce the vocals by let's say 50% rather than entirely removing them. *grin* Thanks to Gale and two others on the users list for triggering this idea. Since my Windows computer is coming back tonight, could someone please check that it works as intended, and commit if desired. Thanks - David

Trying to download a .ny file from sourceforge

David R. Sky — 2008-12-03T08:12:59

Hi, Based on a conversation with Gale and a couple other people on the users list, I realized there was a simple yet potentially useful way to upgrade vocalremover.ny. However, the three times I downloaded the file from two separate links from the Nyquist plug-ins repository, the file was complete gibberish, even though the plug was fine when reading it on it's "page", which was the link I tried to download it from. There was something new I haven't seen before - the filename given to me to download as was vocalremover.ny.gz - what's the .gz extension for? Could someone please email it to me or post it here as an attachment - even though my Windows computer is away until tomorrow night all I need to add is one input line, one extra line of code, and change one specific value throughout the plug. Thanks - David

Compile error in FFmpeg.cpp

Gordon Weast — 2008-12-03T02:11:27

I updated from CVS this evening and got a compile error in FFmpeg.cpp. This is on Ubuntu 8.04 with gcc. Line 518 in FFmpeg.cpp ... // Attempt to load avcodec_init from it. if (avformat->HasSymbol("avcodec_init")) { ... It should be: // Attempt to load avcodec_init from it. if (avformat->HasSymbol(wxT("avcodec_init"))) { The wxT string conversion was missing. Can someone make the change and get it into CVS?

WMA exports mostly don't play on Windows ifmetadata added

2008-12-01T03:08:19

I'm forwarding below a user report about exported WMA files not being playable if tags are added (except for "Year", though that is not written anyway because it is not supported by FFmpeg). I only just got round to testing with ffmpeg at command line, but it looks if it might be an Audacity issue, because command line export with tags is OK. At the command line I have to force the codec to wma2 (else it defaults to mp3), and force tag passing from the metadata in the input file (I couldn't find how to write new tags). So with input.wma which contains Title and Comment tags, I do: ffmpeg -i input.wma -acodec wmav2 output.wma -map_meta_data outfile:infile Then output.wma has the correct two tags and plays fine in WMP 11, Foobar and VLC (which both report the codec as wma2). But if I import input.wma into Audacity and export it, or create a track in Audacity and export it as WMA with Title and Comment tags, neither of the three players will play it. VLC now can't see any codec details, though Foobar can (Foobar's reported error is below). Gale | From Rupert Russell | Mon, 24 Nov 2008 13:05:43 +1100 | Subject: Beta_Feedback - Problem with WMA files - Not supporting Artist Information Thanks for the report. The FFmpeg library (which handles the export) only supports writing of WMA metadata for Track Title, Author and Comment (plus Copyright, which Audacity does not support). If you export the track with just the "Year" tag entered in Metadata Editor, the file will play, but otherwise I agree most or all players won't play the WMA file if you add metadata. In Foobar the error given is: "Decoding failure at 0:00.000 (IWMSyncReader::GetNextSample failed (C00D080D)) " It's very likely this is a bug in FFmpeg itself (at least in part), but we will check. Meantime, I suggest you add the metadata you require in Windows Media Player, or by right-clicking over the file in Explorer > Properties: Summary tab.

NewTime Scale Effect

Gale Andrews — 2008-11-28T04:58:36

Thanks for this, Clayton. You can certainly play with this for hours instead of getting any work done :=) Some points: * It seems you can get the same change in the "half steps" boxes and the "cents" boxes by entering different figures in them e.g. 0.5 half steps is the same as 50 cents if I've grasped it. I found this very confusing. Mightn't it be better to have integers for the half steps and then cents as now? Or save some space and just "half steps" and do away with the "cents" boxes? It should be obvious that 1.5 half steps is one half step and 50 cents. I'd rather see the space taken by an alternative "percent" calculation (as per Change Pitch) instead of these cents boxes. * Why the limitation on -/+ 50 in the cents boxes that forces you to use the half steps boxes if you want 80 cents? * As regards text, can we have "-12 to 12" instead of "-12:12"? And can we have "semitones (half-steps)" to match with Change Pitch? Semitones is I think much more common usage in Europe (and even generally). And can we have "Tempo Change" not "Rate Change", so it matches with the progress dialogue and Change Tempo? * I did not play that much, but on a clip that had drum and cymbal strikes plus piano arpeggios, artefacts were much more noticeable at higher settings on the quality slider (worse to my ears than very low settings). Default quality was very impressive. Can you provide any input for documentation of the quality slider, and when to use sharpening? * Clearly this is much better than SoundTouch for constant Tempo and Pitch changes, both in sound quality and freedom from the frustrating length changes in Change Pitch. Is the downside only processing time, or might it actually crash really slow machines? * Could this effect be extended/modified to provide an alternative for Time Track as well (pitch changes in sympathy with tempo)? Obviously Time Track has more flexibility because you can add envelope points, but it's very buggy, and I think little used or understood.

reported incompatible FFmpeg library on Windows2000

2008-11-22T21:04:45

A user of the 1.3.6 Unicode Beta Release on Windows 2000 has reported that the recommended FFmpeg binary: http://lame.buanzo.com.ar/ffmpeg.win32.2008.10.17.git-ddb6d09.audio-only.gpl.bin-dependencies.exe is refused as incompatible as follows: "The library you point to below, is the one I was trying to use. After receiving your e-mail I did the following: Uninstalled Audacity. Removed the library files. Re-downloaded the library from the link you provided. Re-installed audacity. Unpacked the newly downloaded library files into the audacity directory. Tried "Find Library" and got "Failed to find compatible FFmpeg libraries". Used Browse, and the selection dialog shows the file avformat-52.dll in the audacity directory. I select it, press Open, then OK, and get "Failed to find compatible FFmpeg libraries". I've confirmed he appears to be using our current release. Any reason for a Windows 2000 specific problem, and could anyone on that OS try it?

Computing waveform value at a pixel

Mat Mikul — 2008-11-21T19:32:28

Hello, How is the actual waveform value at a specific pixel is computed? For example, if I want to draw the waveform and show 5 points per second, I should look at the samples around each point (some function of number of samples per second and number of points per second). Now to compute the actual value, is it standard to average all the values around the point or max or min? ------------------------------------------------------------------------- This SF.Net email is sponsored by the Moblin Your Move Developer's challenge Build the coolest Linux based applications with Moblin SDK & win great prizes Grand prize is a trip for two to an Open Source event anywhere in the world http://moblin-contest.org/redirect.php?banner_id=100&url=/

Normalize only works up to -24db?

Michael Chinen — 2008-11-21T05:27:41

I found this behavior a bit odd. The code in EffectNormalize::StartProcessing() explains why this is happening. NORMALIZE_DB_MIN is -240, but because mLevel is multiplied by 10, it means 24 db, not -240db. Is there a good reason or convention that says you should limit normalize at 24db? In any case, we don't notify the user of the truncation. float ratio = pow(10.0,TrapDouble(-mLevel*10, NORMALIZE_DB_MIN, NORMALIZE_DB_MAX)/200.0); ------------------------------------------------------------------------- This SF.Net email is sponsored by the Moblin Your Move Developer's challenge Build the coolest Linux based applications with Moblin SDK & win great prizes Grand prize is a trip for two to an Open Source event anywhere in the world http://moblin-contest.org/redirect.php?banner_id=100&url=/

Export from the manual wiki

Richard Ash — 2008-11-16T21:02:58

We need to resolve the issue with exporting the manual for 1.4.0 from mediawiki to other formats. For anyone who doesn't know, Dominic wrote a mediawiki -> xml -> pdf toolchain for Audacity, which is currently broken for reasons we don't really understand, probably because it can't absorb some bits of mediawiki syntax. It's written in python, and we don't have the resources to fix it in the short term. The problem of wanting to export mediawiki to other formats is not unique to Audacity, however. It essentially affects a large number of mediawiki using organisations. As a result there is now some fairly serious effort being expended towards a "proper" solution, in the form of the Collection extension. http://www.mediawiki.org/wiki/Extension:Collection This offers a way to specify a set of wiki pages which are to be exported, then render them to a number of formats, including PDF and ODF. xhtml export is supposed to be on the way (it's in the back-end libraries, although it may not work), from which simplified html export could be adapted. I've been using this on a project at work, and in general it seems to be a solid project, with a small but responsive team developing it. This means that in general the burden of making it work with the content we have on the manual wiki doesn't fall on us: 1) because the majority of things we do will have already been done elsewhere and fixed before we hit them. 2) we can report bugs out to someone else when we do find them. The funding for the development is coming from a print-on-demand outfit in Germany who see themselves getting a return from people ordering print copies of wiki contents. So there is a well maintained path to be able to print hard copies of the manual if we wish to (we would have to negotiate with them if we wished to make any income from such a scheme). This is not an integral part of the set-up, especially if we run our own rendering server rather than using theirs. Anyway, my point is that I think we should install the extension on the manual wiki and see where we get to, and what works/doesn't. This might provide a low-effort route to unblock one of the P1 issues to release.
