Ideias para novas FAQs
ToDo develop responses for these proposed FAQs and migrate them to the published part of the page.


 * Steve 19Nov13: Trebor posted a useful link in a |recent forum post to a Wikipedia article about | Generation Loss. We frequently get asked about loss of sound quality when editing MP3 files and MP3s increasing in size after editing in Audacity. "Generation loss" is an important part of the answer. Should we have a FAQ about it?
 * Steve 19Nov13: Should we have a FAQ section about "Sound Quality"?
 * Why did my exported MP3 get larger after I applied an effect to it?
 * Steve 26Jul11: Perhaps there could be a section for using Audacity with other applications, such as Skype, YouTube, DAWs and Games

Please quote the full three-section version number of Audacity as found at Help > About Audacity (or Audacity > About Audacity on a Mac computer).

Os exemplos podem parecer como:

(A) "For this work I used version 1.3.14 of Audacity(R) recording and editing software[1]."

(B) "Audacity Team (2012). Audacity(R): Free Audio Editor and Recorder [Computer program]. Version 1.3.14 retrieved December 20th 2011 from http://web.audacityteam.org/ [1]." .

[1] must link to the following verbatim citation:

The citation could be in a footnote, or linked to on a Credits page or similar. Alternatively you could append the citation verbatim underneath the arbitrary text for version number.

Also we would ask you to present the word "Audacity" on its first appearance in your actual research text as "Audacity(R)".
