Audio troubleshooting
Each platform out there has its own standard:
- Windows uses Waveform files (.wav)
- Macs use AIFF files (.aiff)
- Unix machines often use SunAudio files (.au)
- There are two emerging high-quality (CD) standard called
Audio MPEG (.mp2) and RealAudio (.ra or .raw).
Windows
If you don't have a sound card, install the pc speaker driver
speak.exe available from
Dec
or
ftp.cdrom.com.
Common formats (AU, WAV, AIFF) can be handled by
Wham,
wplny11.zip.
If you need Audio MPEG capability, try out
mpgaudio.
Mac
Common formats (AU, WAV, AIFF) can be handled by
sound-machine
or
SoundApp.
If you need Audio MPEG capability, try out
mpeg-audio.
Unix
- Sun Unix (SunOS4 or Solaris2)
-
If you want to do
audio streaming
with Netscape (play the files while they are
downloading through the network) you need
xplay, which handles
common AU, WAV and AIFF formats.
Your mailcap file should read:
audio/*; xplay -forkoff -; stream-buffer-size=8000
- Other Unices
-
You will have to do manual conversions with
sox.
For instance, to do on-the-fly conversion to AU
and audio streaming through Netscape,
your mailcap file should read:
audio/x-wav; sox -t .wav - -t .au - > /dev/audio; stream-buffer-size=8000
- If you need Audio MPEG capability (SGI, Sun, Next, 16 bit soundcards/Linux)
-
Install your platform-specific
maplay
binary.
Note: Sun users will need to know if their output device is
high-quality (CD-like) dbri such as shipped with SparcStation10
(external speakerbox) or low-quality ulaw-only amd such as low-end
SparcStation IPX which must use the maplay_ulaw program
instead.
Then add in the mime.types file:
audio/x-mpeg mp2
and in mailcap:
audio/x-mpeg; maplay %s
