Bit Rate Mode
These offer four new ways to control the trade-off between your size and excellence of the released files.
- Preset: This provides you a range of four presets suggested through the designers. Each preset is a mix of various encoding parameters as proven within the table below. Fundamental essentials suggested, simple to use configurations pick one unless of course you've reason to test out other parameters. Like a rough help guide to the claims designed for these presets, uncritical audience with quality equipment may see personal files encoded with Extreme preset to become indistinguishable in the original, and individuals with budget equipment should see little difference in the original file with Standard preset.
The Insane preset is, instead of the utilized by another presets. Files encoded with Insane preset have a fixed 2.2 Megabytes each minute, frequently double how big Extreme preset, with hardly any audible improvement.
- -b is 32 and is applicable regardless of fast or standard setting
- low pass values were incorrect. I show 3.99.3 on Home windows however in 3.98.2, Extreme low pass what food was in a far more reasonable 19500 - I've not found any explanation of the decision in 3.99, only questions regarding it.
(correct for LAME 3.99.3 on Home windows)
Preset | Target killerbytes per second | killerbytes per second range | -b switch
(minimum killerbytes per second) |
|
---|---|---|---|---|
Insane | 320 | 20500 | ||
Extreme | 245 | 220-260 | 32 | 22100 Hz |
Standard | 190 | 170-210 | 18500 Hz | |
Medium | 165 | 145-185 | 17500 Hz |
- Variable: This mode continuously varies the part rate used based on the complexity from the seem, so that they can maintain the standard from the recording in a consistent level. The configurations vary from (greatest quality) to 9 (littlest quality). Each setting defines a variety of bit rates within so it will normally operate, presuming a stereo system track. For any mono track, the accomplished bit rate for every setting will often be underneath the range indicated above.
Level resembles the ultimate preset pointed out above, level 2 resembles Standard and level 4 to Medium presets. Variable bit rate offers the highest quality in comparison towards the Average and Constant bit rate options in many conditions (very quiet music is a exception). It'll tend to provide you with somewhat more compact file dimensions for any given amount of quality, however the actual file dimensions can not be precisely predicted ahead of time.
- Average: This sets a known, average bit rate for that file, but in this particular average permits some fluctuations in bit rate to mirror the relative impossibility of encoding the file. This doesn't provide as consistently high an excellent as variable bit rate, but is usually more suitable to constant bit rate if you want to know pretty much what size your files is going to be it provides bit rates from 8 killerbytes per second to 320 killerbytes per second.
- Constant: This sets a continuing bit rate for that encoding, no matter its complexity. From the four bit rate modes, this often provides the worst, least consistent quality for any given quality, however that size is completely foreseeable (observe that when you purchase a higher bit rate, the LAME encoder could use a lesser constant bit rate when you purchase 11025 Hz or lower project rate). Use constant bit rate if you're streaming the file on the internet, because it guarantees the audio cannot stutter because of sudden peaks within the bit rate. The accessible bit rates are identical for average bit rate - the default rate (128 killerbytes per second) provides you with a known quality of approximately 1 Megabytes each minute of mono or stereo system audio.
Quality
Their list allows you choose the part rate in killerbytes per second (kilobits per second) for encoding your file. A greater bit rate always gives higher quality but at the fee for a bigger quality and the other way around. The part minute rates are absolute for average and constant bit rate modes, but expressed like a range for that variable and preset modes (aside from the Insane preset).
Variable Speed
Selection of speed can be obtained when utilizing variable bit rate encoding. It determines the rate and bit allocation programs from the encoding . The default "Fast" option is the same as -vbr-new and it is generally suggested for quality and speed. The "Standard" reduced option is the same as -vbr-old. It's possible this can provide more consistent encoding quality in certain material or if you want to make use of an earlier 3.9x form of LAME.
