BULK UPLOAD REVERB LP LICENSE
Released under terms of the GNU General Public License version 2: An implementation of reverb.lsp by Roger Dannenberg. (setq damping 50) High frequency damping (%) I think they are self explanatory, but only change the number in those first 5 lines, any other changes are likely to break the code.Ĭode: Select all (setq time 2.5) Reverberation time in seconds The first 5 lines (before the License information) are the reverb settings. On stereo tracks it will produce a stereo reverb.
BULK UPLOAD REVERB LP CODE
Here is some code for you to play with (from "Reverb1) that adds reverb. (not easy without learning a bit about Nyquist programming).
BULK UPLOAD REVERB LP PATCH
Note that the major limitation of using the Nyquist Prompt in a chain is that the code in the Nyquist Prompt is not saved in the Chain. You set up a Chain with the Nyquist Prompt (as already described) with "code to apply reverb" in the Nyquist prompt.(For "distortion" you could use the " Leveller" effect on a heavy setting). Unfortunately, without my patch (mentioned previously) you are limited to the effects that are listed in the Edit Chains dialogue, and this does not include reverb or other complex echo effects.

Ogg format offers similar quality as MP3 (often slightly better) and does not have this problem.
This is a limitation of the MP3 format and makes MP3s unsuitable for looping. The MP3 format always adds a little bit of silence at the beginning of the file.Encoding to a lossy format (such as MP3, WMA, Ogg.) should be done as the final step, and it is usually best to keep an uncompressed (WAV) backup of the file just in case you ever want to do more editing. It is always best (whenever possible) to work with uncompressed audio (such as WAV files). If you then either export as MP3, or export as WAV and re-encode to MP3 with an external encoder, there will be some sound quality loss when it is encoded. Audacity only works on uncompressed data, so the MP3 would be decoded (automatically) when it is imported.However if the files are in a compressed format such as MP3, note that: Short files are trimmed very close to start/end of the audio. The method described in my previous post should do a good job with that.

This is the threshold (in dB) for what will be considered to be "silence" at the beginning and end of the track.
