MP3 Options

 

  • In Format

    • This is the format on the input file to the mp3 encoder. It is used so you can check what Out Format you can use for a specific In Format. An audio CD has "44100 Hz - Stereo - 172 kbps". For Rosoft CD Extractor this field should be set to "44100 Hz - Stereo - 172 kbps" to ensure that you select a valid Out Format.

  • Out Format

    • This is the format of the encoded file. The first value is the sample rate, the second is the channel mode (stereo/mono) and the last is the bit rate. High bit rate gives high quality and large files. Low bit rate gives lower quality and smaller files.

  • Encoder

    • See our mp3 plug-in page. 

  • Quality Mode

    • The option sets the quality of the encoder. High Quality gives very good sound but takes more time to encode. Normal giver a fairly good sound and at normal speed. Fast Encoder encodes the file fast but gives a lower quality of the sound.

  • Private bit on

    • This controls the so called value of the private bit. Select this to indicate that this track is the original. Un-select this control if it is a copy.

  • CRC bit on

    • If this control is selected the encoder generates CRC check sums.

  • Copyright bit on and Original bit on

    • Controls the original/copy bit in the MPEG frame header. Select this control to indicate that this tack is the original.

  • VBR on

    • Select this control if you want to use Variable Bit Rate (VBR).

  • VBR Quality

    • Sets the quality of the VBR mode. 0 is the as Constant Bit Rate (CBR). Value 1 is the highest VBR quality while 10 is the lowest VBR Quality.

  • OK

    • Press this button to save the options you have entered in the Registry.

  • Cancel

    • Press cancel to close the form without saving the data in the Registry.

  • Help

  • Padding Mode

    • Certain multimedia and architectures (namely, Microsoft Netshow) have a hard time dealing with blocks of variable size. If you want to transport MPEG Layer-3 content over this system, setting Padding Mode to Never or always will make the encoder generate equally sized frames. Only ISO is guaranteed to write ISO-compliant bit streams with exact bit rates.

  • Allow Intensity

    • Usually you should allow the encoder to use intensity stereo coding, especially at the lower bit rates. However, in special cases, it might be useful to disallow intensity stereo.

  • Allow Midsize

    • Usually you should allow the encoder to use mid/side stereo coding, especially at the lower bit rates. However, in special cases, it might be useful to disallow mid/side stereo. This flag is not supported yet.

  • Allow Downmix

    • Usually you should allow the encoder to Downmix stereo input to mono output. However in special cases, it might be useful to disallow Downmix.
