I know that its done to prevent errors and corruption in files, but what exactly is it? What exactly does it do? greynol Hero Member Joined: 01 April, 2004 Posts: 12,124 Logged Global Moderator What exactly is 'CRC Error Protection'? Reply #1 – 08 July, 2010, 10:25:44 PM It's added to detect errors and corruption. It cannot prevent errors and corruption, let alone repair errors and corruption.http://lame.cvs.sourceforge.net/viewvc/lam.../switchs.html#phttp://en.wikipedia.org/wiki/Cyclic_redundancy_check 13 February 2016: The world was blessed with the passing of a truly vile and wretched person.Your eyes cannot hear. powerstone05 Newbie Joined: 20 June, 2010 Posts: 22 Logged What exactly is 'CRC Error Protection'?

Supported by this Codec Encoding: Yes [.mp3] Multi-processor Encoding: Yes (with dBpoweramp reference) Decoding: Yes [.m2a, .mp1, .mp2, .mp3, .mpa, .mpg, .mpga, .mpx] ID Tag Reading: Yes [ID3v2, ID3v1, APEv2] ID Tag Writing: Yes [ID3v2 (default), ID3v1, APEv2] Unicode Tagging: Yes (id3v2) Supports Album Art: Yes (id3v2) Gapless Encoding & Decoding: Yes Explorer Audio Popup Information: Yes Explorer Columns: Yes Unicode Filenames: Yes Compression Options Lame offers 4 types of encoding: Variable Bit Rate (VBR) files are made up from https://hydrogenaud.io/index.php/topic,82091.0.html 100's of small audio chunks, called frames. Whilst encoding VBR, the encoder decides which bit rate to use for each frame. Bit rates can drop down to lower values when it is warranted (if there is not much sound complexity) and switch up to a higher bit rate when required. VBR files are the preferred method of mp3 encoding, Average Bit Rate (ABR) is like VBR https://www.dbpoweramp.com/Help/dMC/mp3lame.html except constraints are placed on Bit Rate so that over time it averages out to the desired value, Constant Bit Rate (CBR) a fixed bit rate is used throughout the encoding process. Free Format extends the constant bit rate to much higher values (such as 640 kbps), has limited player support. Advanced shows: Frequency - number of samples per second to be encoded, [as source] allows the output frequency to match the input frequency (recommended). Channels: [auto] matches the channels to the source, for 2 channels Joint Stereo is used. Mono a recording with only a single channel of information. Joint Stereo - luckily for stereo compression sound on the left channel is very similar to sound on the right channel, Joint Stereo takes advantage of this similarity to use the savings on the 2nd channel to give higher quality compression. Forced Joint Stereo - forces separate encoding of left and right channels, only recommended when high bitrates are used. Quality specifies how much effort goes into compression, this mode is applicable to all types of encoding. Copyright marks the mp3 file as containing copyright material. Original marks the mp3 file as an ori
produces a better quality output but slows down the audio encoding process. Variable Bitrate Encoding (VBR) Select this option to encode the audio using a variable crc error bit rate, which is considered to produce superior results to CBR encoding. For this mode you must select minimum and maximum bitrates from the respective bitrate drop-down lists. The "Quality" option affects crc error protection the audible quality of the file, with a higher quality yielding a larger file size for the resulting MP3 file. Note that the number 0 will produce the highest quality and largest file size. Channels This selects whether the MP3 file will be Stereo, Joint, Force or Mono. Force means that the encoding process will force ms_stereo for all frames, which is faster. Error Protection This option adds additional CRC information into the MP3 file, and protects against small corruptions that may later develop due to faulty media on which the file is stored.
