1. Introduction

PaceMaker is a component (plug-in) for Winamp3 player, enabling controlling the sound tempo, pitch and playback rate independetly from each other. That is, with PaceMaker it's possible to:

6. Troubleshooting & FAQ

Is there an expiration time limit in PaceMaker3?

No, this version doesn't have a time limit. There was an expiration date in the first alpha release of PaceMaker3, but it was removed because it's likely that this is also the last version of PaceMaker3 component for Winamp3 for the time being due to suspending of Winamp3 player development work by Nullsoft.

PaceMaker doesn't work with audio CD's played in my CD-ROM station.

PaceMaker processes the sound data that Winamp3 passes through it. If PaceMaker doesn't affect your audio CD's, ensure that "Enable CD audio extraction" is checked in "Audio CD Settings" page of Winamp preferences. If this doesn't help, it may also be that your CD-ROM drive can't extract audio data in binary format.

The music has breaks / My PC is too slow

Winamp3 requires quite a lot more CPU muscles than the good old Winamp2. If you have an older PC with say 150..300Mhz processor, you might be better off with the older Winamp version. You'll find Winamp 2.81 at classic.winamp.com and PaceMaker for that version at the PaceMaker page.

Is it possible to use PaceMaker routines in own applications / Is there a command-line tool for processing audio files in batch mode

Yes it is; Please contact the author if you'd wish to receive the source codes or otherwise have more information.

Please notice that I've released an open-source library having similar DSP routines than PaceMaker that can be used for doing sound processing in own applications. See the SoundTouch page for source codes and more details.

There have been queries on how the PaceMaker's DSP algorithms work; I've planned to write a description of the algorithms for quite some time, but have so far been too busy to compelete that. Will do so some day, hopefully...

7. Planned work

Notice concerning Winamp3 future: Nullsoft (the group developing Winamp) has obviously suspended Winamp3 development project. Unless Winamp3 development will be resumed, it's infeasible to continue developing PaceMaker component for a dying player platform, and in this light this will be the last PaceMaker component release for Winamp3 player for the time being. Future work among PaceMaker will concentrate around Winamp2 or some other actively developed player platform.
