-
- Sound Quality
- If you are experiencing poor sound quality there are several simple
- steps you can take to determine the cause. First, use the Connection
- Statistics box to determine if there is packet loss. Packet loss
- during transmission over the Internet is the main cause of poor
- sound quality.
-
- If packet loss does not seem to be causing poor sound quality, you can
- try adjusting the way the RealAudio Player delivers sound to your
- computer's sound card. Choose Preferences from the View menu and then
- select the Advanced tab. You will see check boxes for "Use 8-bit Only"
- and "Use 11 kHz only":
-
- Use 8-bit Only
- ------------------
- Use this option only if there is evidence of compatibility problems
- with your soundcard. The Player normally delivers 16-bit audio to the
- sound card. If the sound card only supports 8-bit audio, the Player
- delivers 8-bit audio. If your sound card fails to inform the RealAudio
- Player that it only supports 8-bit audio, you may hear only random or
- garbled sound when playing clips. Check this option to override the
- 16-bit default and play 8-bit sound.
-
- Use 11 kHz Only
- ---------------------
- Use this option only if there is evidence of compatibility problems
- with your sound card. The Player normally delivers 8 kHz audio to the
- sound card. If your sound card does not support the 8 kHz sampling
- rate, the audio may sound high-pitched or too fast. Check this
- option to instruct the Player to convert audio to 11 kHz before
- delivering it to the sound card. This option increases CPU usage
- slightly.
-
- If you continue to receive poor quality audio, please see our
- FAQ entry on audio quality at:
-
- http://www.realaudio.com/help.html
-
- Select FAQ and from there choose the "Audio Quality" entry.
-
- Please note that to receive RealAudio 28.8 you should have at least
- a 19.2 Kbps connection to your Internet Service Provider. In a
- 19.2 Kbps connection you may hear slight gaps in the audio.
-
- Dial-up users should be sure to keep the network connection preference
- as UDP (the default). In TCP mode, no audio packets are lost,
- but their arrival may be late enough to cause gapping in the audio.
- TCP mode is useful when you are directly connected (via a
- local area network) to the internet.
-
- ---------------------------------------------------------------------
-
- Known Problems
-
- * Starting or quitting large applications while playing
- RealAudio can cause some brief disruption of the playback.
-
- * Playback on some 486/25 SX computers does not work properly.
-
- * The user interface during playback of 28.8 content on slower
- systems may have slow response time. Performance of other
- applications may suffer during playback. To improve system
- performance select the General tab from the View|Preferences menu
- and adjust the Best Audio Quality/Lowest CPU Usage slider.
