CREATIVE AWE64 - Manual (Page 89)

2
For some audio cards, WaveSynth/WG can output sounds at
44 kHz if you select this option in the WaveSynth/WG control
panel.
In addition, for Sound Blaster cards that use one 8-bit and one 16-bit DMA
channels for either playback or recording, the following constraints also apply:
❑ while you are recording a 16-bit wave file, WaveSynth/WG cannot
play a MIDI file;
❑ while WaveSynth/WG is playing a MIDI file, you can record only an
8-bit wave file;
since WaveSynth/WG must play back through the 16-bit DMA channel.
If audio playback or recording is too slow (for example, resulting in
clicking sounds heard during playback), try to reduce the sampling
rate to improve performance.
Half-Duplex Mode
When you select this mode, you can do a wave (including DirectSound)
playback while WaveSynth/WG is playing a MIDI file. But there are some
constraints in this mode:
❑ You cannot play an audio file and record another one at the same time.
❑ Creative FastSpeech playback is not supported.
❑ Wave playback is restricted to the sampling rate conversions that
Microsoft’s Audio Compression Manager (ACM) supports. ACM
will do the necessary sampling rate conversion during playback.
Thus, if you do not have ACM, you cannot play 8 kHz wave files.
❑ You cannot play wave files when Creative Mixer’s LED is active
because LED is doing recording.
(To disable LED, refer to Creative Mixer’s online help.)
❑ The Volume Unit display of Microsoft Mixer is not available.
