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
  Chose from BladeEnc and LameEnc. We recomend you to use LameEnc. 

• 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. Unselect 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.

Options that are valid if you have Rosoft MP3 Encoder installed

Rosoft Engineering no longer sells this encoder due to the huge patent fees MP3-Licensing is charging. A minimum annual fee of US$ 15,000 and then US$ 5 per shipped Fraunhofer MP3 Encoder plug in and US$ 7.5 for every shipped MP3Pro encoder. This is the reason we no only support encoders such as Lame. The Lame encoder is an encoder that produces mp3 files and can be downloaded from Lame's official download page here.

• 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. This mode is only valid if you have the file rsfhgencr.dll in your Windows Folder. This file came with Rosoft MP3 Encoder, Licensed Edition which no longer is sold. However the new releases of Rosoft CD Extractor supports the older editions.

  • 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.
