2.Encoder operation
( Windows )
SoundVQ Encoder (Win)
( Macintosh )
SoundVQ Encoder (Mac)
In order to create a SoundVQ file, first prepare the sound source and store the file on your hard drive. Follow the steps given below to encode the data as a SoundVQ file.
1.Select the source file for encoding. (Source)
Browse button:
Click this button to open the dialog to select the audio data for encoding. When you select a file, the file name appears in the File message box and the sound format of the file appears in the Format box.

Supported audio files are ; ".wav" (Windows WAVE format), ".aif" or ".aiff" (Apple AIFF format). All other formats are judged to be Raw PCM format.

The bit resolution is 8 bits/16 bits and only non-compressed files can be encoded.

When moving a Macintosh file to a Windows machine, please make sure that it is not MacBinary.

If you select a file with an extension other than ".wav", ".aif" or ".aiff," you will need to manually set the file type, bit resolution, sampling frequency and number of channels (Stereo/Mono), etc.

Play button:
Click this button to start playback of the audio data displayed in the File window. This can be used to check the sound and its quality prior to encoding.


2.Specify the output of the encoded result (Destination)
Browse button:
Click this button to open the dialog to specify the destination to which the encoded result will be output. When indicated, the filename is displayed in the File box. Normally, the automatically specified filename will consist of the file name selected for encoding, with the extension changed to ".vqf".
Play button:
Click this button to start playback of the SoundVQ file displayed in the File box. This can be used to check the quality after encoding.


3.Selection of compression mode (Compresssion)
Encode Mode
Selects the compression mode. The compression mode will change according to the audio data file being compressed, as shown below.

Source sampling frequency Compression mode Compression rate
per channel
8KHz 8KHz/8Kbps/ch 8kbit/s
11KHz 11KHz/8Kbps/ch 8kbit/s
11KHz/10Kbps/ch 11kbit/s
16KHz 16KHz/16Kbps/ch 16kbit/s
22KHz 22KHz/20Kbps/ch 20kbit/s
22KHz/24Kbps/ch 24kbit/s
22KHz/32Kbps/ch 32kbit/s
44KHz 44KHz/40Kbps/ch 40kbit/s
44KHz/48Kbps/ch 48kbit/s

Channels
The number of channels that the compressed file will have can be specified as stereo/mono.
It is not possible for the compressed data to have more channels than the original data.
Quality
You may give priority either to sound quality or to compression speed by selecting one of the following three choices for compression. Normally you will select Normal.
The Quality setting that is selected will have no effect on the data transfer rate of the compressed data.

"High" :Sound quality is given priority. The compression speed is the slowest.
"Normal": There will be an equal balance between sound quality and compression speed.
"Low" :Compression speed is given priority. The sound quality may be slightly lower.

4.Enter information regarding the compressed data ( Description )
Title
Enter the title for display on the player. Entry of the Title is required.
Copyright
Enter the Copyright for display on the player. Entry of the Copyright is required.
Comment
Enter any information.
Permissionto save
If chekcked, "SAVE" button of SoundVQ Player is enabled when this SoundVQ file is loaded. User can save it to the person's local-disk.
filename
If "Permission to save" is checked, this filename is used as default filename to save. The last of this must be end with ".vqf".
3. HTML description
The HTML entry to start SoundVQ Player is completed by simply pasting a link on the SoundVQ compressed file (extension: vqf) or SoundVQ locator file (extension: vql).

The HTML entry to start SoundVQ Plug-in is completed by simply pasting a link (w/EMBED tag) on the SoundVQ locator file (extension: vqe)

  • vqf file -> : The compressed file itself is passed to the browser. After all compressed files are downloaded, the SoundVQ player will start.
  • vql file -> : The SoundVQ player will read and acquire the target file location which is described in the vql file. When a vql file is used, streaming playback is possible. With streaming playback, the playback will start much quicker than if the file is downloaded, since the playback starts while the data is still downloading.
  • vqe file -> : The SoundVQ Plug-in will read and acquire the target file location which is described in the vqe file. When a vqe file is used, streaming playback is possible. With streaming playback, the playback will start much quicker than if the file is downloaded, since the playback starts while the data is still downloading.

Sample HTML descripton to start SoundVQ Plug-in.


    <EMBED SRC="xxxxx.vqe" WIDTH=150 HEIGHT=40 AUTOSTART=TRUE REPEAT=TRUE VOLUME=100>

    The file xxxxx.vqe is what is called SoundVQ locator file. It is a simple text file, and describes the location (URL) of the SoundVQ file. Please refer here to know about syntax of the SoundVQ locator file.

    The difference between the vql file and vqe file is only the extension. vql file starts SoundVQ Player, and vqe file starts SoundVQ Plug-in.

  • By setting "WIDTH=2 HEIGHT=0 HIDDEN", you can hide the panel. In this case, contorol will not be possible.
  • "AUTOSTART=TRUE" is the normal setting, causing playback to begin automatically when the page is opned. When "AUTOSTART=FALSE", playback will begin only when the Play button of the control panel is pressed.
  • "REPEAT=FALSE" is the normal setting, causing the song playback to repeat until the stop button is pressed. When "REPEAT=TRUE", the song will playback once and then at the end of the song. When "REPEAT=3", the song will repeat only 3 times.
  • "VOLUME=100" is the normal setting, causing the song playback at volume 100%. You can set from 0 up to 100 as the value.
  • If you write several embed tags in one Web-page, the number of embed tags whose autostart function is enable must be 0 or 1.

SoundVQ Locator file syntax

Files with the extension "vql" or "vqe" are known as SoundVQ Locator Files. These files are simple text files (as opposed to files with the extension "vqf"). If the SoundVQ Player is already installed, right-clicking of the locator file will cause the Editing (E) menu to appear.

6.Known Problems
[ Windows ]
  • When "MWAVE" (used on many computers manufactured by IBM ) is used to produce sound, the sound is fragmented.
  • When a Pentium CPU of 75MHz or less is used to playback a 44KHz stereo SoundVQ file, the sound is fragmented (insufficient processing power). Sometimes this happens to NotePC users w/Pentium 120MHz or worse.

[ Macintosh ]

  • Pressing "STOP" or the "Next" or "Prev" buttons during stream playback may cause operation to become unstable.
  • The SoundVQ Player's "OPEN" button can only open a file. To directly specify a URL, press "Command key + u."
  • To create a list file, use a text editor (SimpleText etc.) in conjunction with the SoundVQ Locator File Converter.
  • In the current version, the "Icon button" does not function.
  • In the current version, the "#preload()" function for vql files does not function.
  • In the current version, the key symbol of the player does not light up.
  • When stream playback is performed using a vql file which contains the URL's of multiple vqf files, there may be cases in which the sound breaks off and the next song begins playback. In such cases, pressing the "Prev" button may cause the skipped song to be played.
  • In the current version, operation may become unstable if the Perfect Play function is turned OFF.
  • Extremely short SoundVQ files (such as less than one second) may not playback correctly.
  • Repeatedly pressing buttons such as "Stop," "Next" or "Prev" during stream playback may cause operation to become unstable.
  • During stream playback via proxy, problems may occur depending on the type or loading of the proxy server or web server.
