I am using Audacity 2.0.0 on Microsoft Windows 7 Enterprise 6.1.7601 Service Pack 1 Build 7601.
I recorded several tracks using a Plantronics C610-M USB headset and exported them as “WAV (Microsoft) signed 16 bit PCM” files. I sent them to our editor to add to a PowerPoint presentation. The editor told me that I should have included the “.pk” files. What are the “.pk” files? When are they created? What did I do wrong?
