When playing files from a SCSI drive that is connected to a SCSI controller that utilizes a DMA channel (such as an older ISA controller) you may experience a warbling effect in the sound playback. This can occur if your sound card uses DMA and its DMA channel is set to a higher number than your SCSI controller.

To fix this problem, set the DMA channel used by your sound card to a lower number than that used by your SCSI controller. For example, if your SCSI controller is set to DMA channel 5 and your sound card is set to DMA channel 7, try reconfiguring them so the sound card uses DMA channel 5 and your SCSI controller uses DMA channel 7.

When Sound Forge software starts, it checks to see if you have a wave playback and record device installed in your system. If you don’t, it makes the appropriate operations unavailable.

If you are sure that you have a sound card installed in your system, check the Audio tab in the Preferences dialog. The setting in the Audio device type drop-down list determines the playback and record device Sound Forge software will use. By default, Sound Forge software uses the Wave Mapper (it may also be called the Sound Mapper) device which should automatically pick an appropriate device for use by Sound Forge software. If the playback or recording device is set to (None), Sound Forge can not execute the corresponding operation.

Sound Forge software allows you to load many different types of sound files, including those that your system may not be capable of playing. There are a variety of reasons that your sound card may not be capable of playing a file:

  • Some sound cards only allow playback and recording at specific sample rates. Typically these rates are limited to 11,025, 22,050, and 44,100 Hz. If you try to play a file that is 32,000 Hz, the sound card will not allow you to play it.

  • If you have an older sound card that supports only mono playback, simply convert any stereo files to mono and you will be able to play them.

  • If you have an older sound card, it may only support 8-bit playback. If this is the case simply change the bit depth of the file to 8 bits.

Most sound cards come with multiple inputs from which you can record sound. These may include microphone, CD, auxiliary, MIDI, and line inputs. Although some cards record from all of these inputs at the same time, many cards require you to choose a recording device (also known as the input source). These cards come with software that allows you to pick which device is the input source. Please refer to your sound card manual to determine how to set the input source.

Most sound cards also come with some kind of application that controls the input level of the recording device. You may need to increase the level of your input sources in order to record from them. Again, please refer to your sound card manual to learn how to adjust these levels.

When Sound Forge software is recording or playing audio data, it moves large amounts of data between your hard drive and your sound card. If Sound Forge software can’t move the data fast enough, you will hear small gaps between blocks of data that typically sound like clicks or puttering. Please see Optimizing Sound Forge for information about reducing the overhead during the time Sound Forge software is moving sound data.

If you experience gapping or glitching when recording multichannel audio, try increasing your buffer size. You can increase the Record buffering setting on the Audio tab of the Preferences dialog or click the Advanced button on the Audio tab of the Preferences dialog to increase your device’s buffers.

Sound Forge software works to prevent gaps during recording and playback. As a result, there may be delays between the time that you click the Stop button and the time that playback actually stops. Note that you can always press and hold the Escape key to stop record or playback no matter how bad the situation is. Just be a little patient and wait a few seconds. These delays are usually only observed when one or more components of your system can not keep up with the data rate. Typical faults are:

  • Very slow (older) hard drives.

  • Poorly written sound card drivers.

  • Setting your storage directory to a slow device such as a network drive or a compressed hard drive.

If at all possible, use the fastest uncompressed storage device available with Sound Forge software. For more information on configuring your system, please see Optimizing Sound Forge.

This is caused by a bug in the Turtle Beach Multisound and Tahiti sound card drivers. Contact Turtle Beach for updated drivers.

Some sound drivers incorrectly play sounds with sample rates that are not supported by the sound card hardware. For example, a sound that is supposed to play at 13,000 Hz might be played at 11,025 Hz instead. This will cause the pitch to be lower and the playback time to be slower than it should be.

Contact your sound card manufacturer for updated drivers.
