MP3 - Codec settings

The MP3 (MPEG Audio Layer 3) codec is a lossy audio compression format designed to compress audio data while maintaining acceptable sound quality by removing inaudible or hard-to-detect sounds that the human ear cannot perceive in order to reduce file size.

XMedia Recode uses LAME MP3 encoder.
LAME is one of the best MP3 encoders that you can use for converting audio.

Mode

Specifies whether the audio track is converted or copied.

Codec

Specifies which audio codec is used for encoding.

Language

Sets the language that the player displays when playing.

Delay(ms)

Sets the stream delay.

Sample rate

Specifies the sample rate.

The higher the sample rate, the richer the sound. The values are between 8000 and 48000 Hz.

Rate control mode

• CBR (Constant bitrate)
• VBR Default
• VBR Old
• VBR New
• VBR MTRH
• VBR ABR

CBR (Constant bitrate)

Bitrate

Sets the bitrate. A higher bit rate improves the sound quality but also increases the size of the file. Values are between 32 and 320 kbps.

VBR Default

Minimum bitrate

Sets the minimum permitted bitrate. Values are between 32 and 320 kbps.

Maximum bitrate

Sets the maximum permitted bitrate. Values are between 32 and 320 kbps.

VBR Quality

VBR quality is denoted from 9 to 0, with 0 being the best.

• VBR 0
• VBR 1
• VBR 2
• VBR 3
• VBR 4
• VBR 5
• VBR 6
• VBR 7
• VBR 8
• VBR 9

Channels

• Mono
• Stereo
• Joint Stereo (Analyzes the differences between the right and left channels and removes the duplications, allowing better compression.)

Quality

• Normal(Q=5)
• Low (Q=9)
• High (Q=2)
• Voice
• R3Mix Preset
• Very high quality (Q=0)
• -alt-preset standard
• -alt-preset fast standard
• -alt-preset extreme
• -alt-preset fast extreme
• -alt-preset insane
• -alt-preset ABR
• -alt-preset CBR

Highpass (Hz)

• Set highpass filter cutoff below frequency

Lowpass (Hz)

• Set the lowpass filter cutoff above frequency
