On Windows systems, you may receive "Error while opening sound device" when you try to record. Set DMA mode for the hard drive on Windows and Linux, hardware acceleration for the video card and avoid sound card interrupt sharing.A faster processor or more RAM could help solve the problem.Whatever the audio device, ensure it has the latest drivers as supplied by the motherboard or device manufacturer (as appropriate).connect directly to a USB port, not a hub. If you are using a USB recording device.Set Audacity to a higher priority in the operating system.Consider creating hardware or software profiles that load only essential hardware and services for a recording session. On Windows, regularly defragment your hard disk drive (this should happen automatically on Windows, but do not schedule defragmentation during a recording).In particular, stop anti-virus applications scanning the Audacity Temporary Directory. Quit as many other other applications or processes as possible.Some may have no effect on a skipping problem, others may have a cumulative beneficial effect, so try them all. There are many possible actions you can take. Audacity tells you how much longer you can record for (based on available disk space) in the Status Bar at the bottom of the window. Choose the local drive with the most space. Use a local drive with sufficient space: Set the path to the Audacity temporary directory to a local hard drive because these are usually faster than external USB drives.A single instrument or solo vocal should usually be recorded in mono and can be panned in the stereo field later using Audio Track Dropdown Menu. Either of these actions halves the amount of data Audacity otherwise has to write. Reduce the amount of audio data being written: Choose 16-bit Sample Format in Quality Preferences and set recording channels to mono in Device Toolbar (unless you need stereo).On Mac using Mavericks or later, it may be necessary to reduce audio to buffer, possibly to zero. Increase the default "Buffer length" setting of 100 milliseconds in Devices Preferences.Turn off Transport > Transport Options > Software Playthrough (on/off) unless it is essential you hear what is being recorded.Minimize the Audacity window whenever you have no need to see it. Turn off View > Show Clipping while recording. Reduce screen redrawing: Zoom out to at least the entire length you will be recording, or in Tracks Preferences, uncheck Auto-scroll if head unpinned.You may not hear skips while listening during the recording, but you will hear them on playback. If it sounds like recording is skipping, or small fragments are sometimes missing, this means that Audacity cannot write the audio to disk fast enough to keep up with what it is recording. So Audacity could now appear much worse than previous releases, when in actual fact Audacity is just alerting you to a problem that you previously would not have been aware of - or might have put down to a bad microphone or poor recording technique. You may have been experiencing dropouts and not noticing, they are not discernible while recording only on playback.
