If you intend to apply any "processing" (apply any effects), then it is impossible to do that entirely 100% losslessly (in any program), because the processed samples have to be rounded in some way to 16-bit or 24-bit sample values. This is the case even for simple effects such as Amplify ...

I don't think the Guitar Rig VST fully supports Audacity. The 32-bit version "may" work to some degree, but the 64-bit version definitely will not work at all (because Audacity on Windows is currently 32-bit only). There is a Free Guitar Rig Player available from Native Instruments. Audaci...

How did you install Audacity? (If you installed it from the main repository or a PPA, then it may have been updated from a version that worked to a version that doesn't. If you installed it from a deb, or built it from source, then that will not be the case.) Do you also have a generic Linux kernel ...

What happens with the command:

True! I forgot to say that. I checked that before and this is what appears there: ============================== Default recording device number: -1 Default playback device number: -1 No devices found and that is even after a reboot? What do you get from: aplay -l (that's "hyphen, lower case L...

Try this: 1) From the "Help" menu, select "Audio Device Info". When the info appears, save it as a text file. 2) Log out and back in again (or reboot) 3) Repeat step 1. Then post the two text files with your reply (see here for how to attach a file to a forum post: https://forum....

Audacity is not available for mobile devices. The main reason being that the GUI toolkit (WxWidgets) on which Audacity is built, is not available for mobile platforms. Some additional information here in the FAQ: http://manual.audacityteam.org/man/faq_about_audacity.html#mobile The manual for Audaci...

Avatars have been disabled because too many people were abusing the feature for distributing spam and we don't have the resources to be constantly monitoring their usage. Available profile settings may be found in the "user control panel" (link near the top left of each forum page, just be...

What is an analog white noise? One of the most common ways to generate "analogue white noise" is to reverse bias a transistor. Other methods include using saturated emission vacuum tube diodes, thermal resistors or reverse biased diodes. The main benefit of analogue circuit noise generato...
