So you can see how this guide focuses on quality. And you can't get audio quality any better than lossless. Of course you are additionally able to extract to uncompressed WAV, this does not depend on the selected compression scheme. The LAMEMP3 encoder is so highly developed that even big companies like Sony are ripping off parts of its source code(shame on them). In the next step you can select between the four most often used compression schemes: MP3 and WMA (for lossy compression) and FLAC and WMA Lossless (for lossless compression). They are often used to store CDs on hard disk drives for archival purposes, as they allow bit-correct reproduction of a CD, even though they reduce the size of the file to around half the size of an uncompressed WAV file. FLAC, WMA Lossless, Monkeys Audio or Shorten have no loss in audio quality, but usually use up to around 6 MB /minute storage space. MP3, WMA, Ogg Vorbis are so called lossy formats, they can bring down the file size to small amounts, but there is some loss in sound quality included in this process.
For that, EAC can use various externally provided encoders, e.g.

to the well known MP3 files for your portable music player (around 1.5 MB /minute). Important: Depending on your needs you can either extract the CD tracks completely uncompressed into so-called WAV files, which need around 10 MB/minute storage space.

It has his own technology such as multi-reading verification and AccurateRip that does a great job, surpassing many commercial alternatives. When EAC encounters a section of a CD that cannot be ripped due to physical damage, it allows you to skip that portion and jump to the other one. An example was given in this article (see section 5). The main difference between EAC and other similar tools is the high accuracy when it comes down to rip/grabb content from damaged CDs or DVDs. However, you can use it for many others too such as AAC, Ogg Vorbis or even for losless formats (FLAC, ALAC and others with the proper external encoders). For WAV and AIFF input files, using -m m will always produce a mono. In this article, I converted a couple of tracks from a CD in WAV format directly to MP3. To encode a stereo PCM input file as mono, use lame -m s -a. EAC can convert tracks from standard CDs to other formats. It was created back in 1998 by Andre Wiethoff and since then he released new and improved versions.

Scalefacts, etc.EAC (shortcut to Exact Audio Copy) is a free audio grabber (for personal use - not commercial) or better said a CD/DVD ripping program for Microsoft Windows. VBR_noise_shaping() find_scalefac() (computes desired_gain)Įstimate largest possible value of global_gain The actual flow chart looks something like this: VBR_quantize() determine minbits, maxbits for each granuleĪdjust global quality setting based on VBR_qīits = VBR_noise_shaping(): Encodes each granule with minbits max_frame_bits) If it does, lower the quality and repeat steps 2,3 and 4 for the granules that Total number of bits for the whole frame does not exceed the maximum allowed. step 6: VBR_quantize() in vbrquantize.c After encoding both channels and granules, check to make sure that the desired_gain The amount of gain needed so that if gain maximum_bits: decrease global_gain, keeping all other scalefactors Values of gain (more negative) mean that more bits are required to encode theĬoefficients, but the quantization noise will be (usually) smaller. Best EAC Setting For Best MP3 Quality Reply 19 21:39:05 Hey FulciLives, t0nee1 here from VH, nice to see you here.I have to tell you, I used to rip to -b320, but now based on listening tests via foobar I now mainly use, -V2 and as low as -V5 for my portables.That seems to float my boat and make my toes wiggle. gain MDCT coefficents are scaled by 2^(-.25*gain) before quantizing. Thanks for the additional information mate. I thought that if the user manually added a switch related to the bitrate that would be enough to ignore or bypass what's in the dropdown list option from EAC. Using -B with other than 320kbs is not recommended, since even aġ28kbs CBR stream will sometimes use frames as large as 320kbs Oh really Well I didn't know EAC would enforce to a minimum bitrate when using the 'LAME MP3 Encoder' parameter scheme. "-v" and "-h" are not necessary when using -V. VBR mode automatically uses the highest quality option. Suggested usage: lame -v -V 2 -b 128 input.wav output.mp3
