Jak otevřít .pk .cpk spk. ???

Adobe Audition CS5.5

a máte s tím zkušenosti ?? v cs 3 mi to nešlo

Nemám, ale:
*.pk = Audition Peak File

Contains the visual representation of an audio waveform for a corresponding audio file; generated automatically by Audition and Cool Edit Pro when an audio file is opened; saved in the same folder as the original audio file.

By default, peak files are generated for all audio files opened in Audition 2.0. This speeds up the waveform display process since the waveform only needs to be generated the first time. You may turn off the automatic peak file generation by choosing "Edit→Preferences→Display." Then deselecting "Save Peak Cache Files."

Adobe acquired Syntrillium in May 2003 and rebranded the program Cool Edit Pro as Adobe Audition.

Odkiaľ máš tie súbory? Netreba k tomu aj odpovedajúci audio súbor, lebo podľa popisu to je akýsi cache súbor na zrýchlenie otvárania audia...

a *cpk, *.spk budú zrejme pochádzať z nejakej hry...
