    I come at this issue from a different set of priorities. I want my ripped music to be the highest quality possible because this is a library of music that I will maintain my entire life and pass on to my kids. I rip everything in FLAC on a well equipped home PC with tons of storage. I use a program called Media Monkey to rip and organize the collection. Media Monkey also has the ability to automate the process of converting the music I select to lossy formats for loading on MP3 players, CD's, and DVD's. The user interface is not the best but the program features are very good.

    Bottom line for me is the initial rip of a CD has to be highest quality because once converted to a lossy format, there is no going back to the original.

    I rip stuff to FLAC for archival (and eventual media server) purposes, but also to the highest quality VBR (variable bit rate) MP3 setting using LAME. VBR only uses as high a bitrate as is necessary at any point in the track. It usually results in a substantial saving in file size compared to a fixed-bitrate MP3, with no loss in quality. I've only found one hardware MP3 player that balked at VBR, the Genica MP3 CD discman.

    You should also insist on using a ripper that verifies quality using the AccurateRip database. EAC and DBPoweramp are a couple. CUETools can verify wav or flac files against the AR database, and tries harder than EAC to find the correct offset.

    With files acquired from "other" sources, quality rips should be accompanied by a log file that confirms there were no errors in ripping. Choose albums encoded in FLAC, APE, or other lossless formats if possible. (If you get an album that's compressed as a single track with cuesheet, and want to split it into tracks, CUETools can split it.)

    Just one thing, though. Bitrate and bandwidth are not directly related. A 20 kHz sine wave could be encoded perfectly adequately with a very low bitrate MP3. More complex high frequency waveforms like cymbals require much higher bitrates to encode transparently.

    Here's my two cents...

    MP3, no matter what bitrate is chosen, is lossy...plain and simple. There will be data removed and/or compressed when using it.
    Upsampling, despite whatever quality your starting off with, will actually improve the sound reproduction...
    Imagine an analogue sound wave...nice and smooth and rounded...a 'wave'. When digitally recoded (to CD), this wave is sampled along the waveform at certain 'points'...sample rate. 44Khz sampling takes a sample of the audio 44,000 times a second.
    Now being digital, there can only be 1's ans 0's...on or off. The sound is reproduced not as a smooth wave form, like the original analogue audio, but something that more resembles a step ladder...the lower the sample rate, the bigger these steps are.

    Now if you upsample this exact same data to a higher sample rate, you add more 'steps' to the wave form. The more 'steps' you use, the closer you get to a natural analogue sound wave..and of course, this will sound more like an actual analogue sound wave. (this of course isn't taking in to account the amount of data that is stored for each sample...either originally, or after upsampling).

    The first few pages of this excellent pdf illustrate how this looks like...

    As for all my music? Being a Windows based PC, I convert all my audio to WMA Pro lossless...whether it be losy based MP3's, or lossless FLAC (which constitutes 90% of my library), WMA audio files work very well in Windows and properly store all the id3 information.
    I also use Centrafuse, so I'm also limited with the playback engine as well...I would prefer to use Foobar with SRC upsampling and ASIO with a VST crossover network...but CF3 still won't allow the use of different playback 'devices'.

    it may be lossy in that it doesnt convert every time value to discrete time which would be impossible, but it can encode and decode with an exact reproduction of the source. Look up the Nyquist theorum. It doesnt make any sense to store every data point when fewer makes the same output.

    Hi, I'd like to use foobar to centrafuse 3. Is it posible now? Is there an application or plug-in that allows this function?

    Thanks!!!

    this might be a better question on a centrafuse forum. they will have better knowledge of what works with cf

    Lol, talk about reviving an old thread!

    PS: Whoever it was that all those months ago said you can up the bitrate of MP3 so that it is not lossy needs to research what the CoDec actually does. It will always take data out, therefore it's lossy.

    I asked on their forum too but it seems that nobody have done a plugin for this....

    Switch to Riderunner if it's that important to have choice in audio players.

    BTW, MP3 is lossy but 2k1toaster is confusing sampling rate with storage capacity. If the sampling frequency is the same it does not affect upper frequency the way he describes it. The storage does however because the algorithm has to use the space the best it can so it will make more compromises in the upper end where it is hard to catch these differences. This is where masking (low level sounds hidden by higher level sounds) comes into play, and the understanding of the human hearing--what will the human hearing not notice is missing? Settings like VBR vs CBR and stereo vs Joint stereo..etc etc.

    BTW, there have been numerous studies done on supposed "quality" of mp3's but in blind tests the majority of music has statistically undetectable differences to the uncompressed version. There are those who believe what they want to believe though it is ridiculously hard to change someones beliefs or biases.

    I used RideRunner too with foobar and it works fine but I've just bought Centrafuse's license!!! I'd like to use it now!
