| Summary | 0002235: Warp in ardour | ||||
| Description | No se ingles, no se hablar ingles pero les reegalo estas direciones donde ustedes pueden ver la herramienta que tendria que tener ardour Not English, not speak English but I reegalo these addresses where you can see the tool you would have to take ardour WARP EXPLICATION: http://www.ableton.com/pages/tips/2004_05 WARP IN ACTION: http://es.youtube.com/watch?v=7F0Dcs-sias http://es.youtube.com/watch?v=hNevsn8Pbxo http://es.youtube.com/watch?v=hvVBnO2FwMc http://es.youtube.com/watch?v=fI4EAWVruwc It is a very useful tool paul Posts: 676 Joined: 2006-03-16 This is a fascinating idea This is a fascinating idea but I cannot imagine adding it to Ardour until some time after version 3.0 comes out. Most people don’t know that Live is running a granular resynthesis engine all the time, which makes transformations like this rather easy. They also have a the possibility of a BBT ruler for every track, which ardour currently does not have. This makes certain aspects of the warp marker idea easier to implement. Please file the idea in our bug/feature request track with a link back to this page, and that way it will not be forgotten. Thanks, Viva Ardour | ||||

For what it's worth, there is at least one open source live warping library available now: - Soundtouch - http://www.surina.net/soundtouch/ - Rubberband - http://www.breakfastquay.com/rubberband/ Both of those are used in Mixxx for live stretching, and work very well with a ±15% stretch, and reasonably well outside of that (good enough to be useful for many genres, but not all). There's also Paulstretch, for extreme stretching, but I doubt it's very useful for Ardour. |

Here a video how it is done in cubase: https://www.youtube.com/watch?v=w3qSloN7h2w I like this way. Also in combination with pitch detection+correction (called "variaudio" in cubase). The rubberband library would be a good choice as a foundation to implement such a feature. A typical workflow: - You record some tracks with musical instruments/voices - you notice some timing-problems in single tracks - you drag some waveform-position with wrong timing to their correct position (possibly snap to musical-rasters) For the implementation there could be different rendering quality-settings or algorithms for live-preview and mixdowns. Some musicians may say, "simply record the track again without errors". But I say, this software-workflow above is so easy and effective, and gives very good results. |

Ardour already uses Rubberband. We replaced our older use of Soundtouch because the latter had way too many artifacts. Most/All (?) proprietary DAWs that do this use ZPlane, which is not usable in a GPL context, and is significantly more sophisticated than Rubberband (or Soundtouch). It is a product of nearly 10 years of highly focused development by people who have specialized in this one domain. |

|
What are the reasons, you think, that rubberband would not fullfill the needs for such a feature? |
|
|
rubberband can provide the API required. the quality of the results is the issue. anyway, the hard part of this is the GUI, not the backend stretching. |
|

Thank you for the explanation. Yes, I believe, that it would be hard to implement a gui for this. But perhaps in the future, someone is motivated enough to do it. It's a killer feature in my opinion. |
