I always keep the flac files in my library so I can convert to mp3 for mobile use and not have to worry about going back the other direction But do you think its worth the effort to rip a cd to flac for my library rather than just buy mbps mp3 directly? Re: When does an mp3 file "lose data" Post by rivorson » Mon Nov 26, am That's correct, all the loss of quality is done when the file is created, though as Peke says it's unlikely you'd hear any difference if encoding above kbps.
Playing the file and changing the metadata doesn't change the audio contents in any way. Whether it is worth ripping the CD or buying the mp3 depends on your circumstances.
Pro mp3: Flac is much larger than mp3 so if you have a laptop with limited storage then the mp3 would be good. The difference between flac and a kbps mp3 is imperceptible. Doesn't require additional conversion to use on other devices like phones. Most mp3s already have metadata at the point of purchase. Pro flac: Keeps the full quality of the source audio. There are better formats available. Can be converted to any other format in the future. For example if you decide that you'd rather use aac audio on your phone next year then you can just change your auto convert settings and have that format.
If either format stops being supported in the future, flac can be converted to another lossless format and still retain full quality. Converting mp3 to another lossy format would result in additional loss. If you already own the CD then ripping it can be done with no additional cost. The greater compatibility of flac going forward as an archival format seems like one of the most convincing reasons. All the cd's I own are already ripped to flac so I'm thinking of future purchases when considering cd to flac vs mp3.
Sometimes the cd's are actually cheaper so its more the question of the time to rip and all The article could seriously use a horde of HA members to edit it into shape, however. Just Elliot, you around? I just deleted this bit of idiocy. It's digital data. It cannot "suffers a loss of information over time" any more readily than any other type of data, audio or otherwise. However, beware of high density neutrino fluxes. Does not only affect mp3 files. These come in many different forms such as loss of bandwidth, pre-echoes, and post-echoes, double-track effect, Dynamics and phase shift and weakened low end.
Now, at kbps, MP3s filter the higher frequencies very crudely, discarding frequency content anywhere above approx. The iTunes MP3 encoder goes as far as creating distortions in this frequency range so in order to maintain full bandwidth through the iTunes MP3 encoder you must have a bit rate of kbps or higher. Even if the quiet one happens first it will be masked by the louder one if there is only a small interval of time between the two.
The masking threshold is the sound pressure level needed to make a sound audible to the human ear when in the presence of another sound known as a masker. If the sound being masked exists beyond the masking threshold then it becomes audible and we hear it as a pre or post-echo. This most often occurs with sounds from percussion instruments but is likely any shorter transient burst of noise when encoded to a format such as MP3.
There is a psychoacoustic element that means one often hears the pre-echo but not the post-echo. Forward temporal masking is much stronger than backward temporal masking which results in the post-echo being drowned out by the transient.
The effect of this is most noticeably heard on vocals, creating the illusion of the voice being double-tracked. The nature of perceptual audio coding is to remove frequency content that we are unlikely to hear. The result of this can sometimes mean that our perception of the remaining frequency content can be altered. The relative phase or timing of frequency content can be changed which can affect stereo imaging or even the transparency and clarity of the material. One of the issues the MP3 format is most known for is making a banging bassline sound timid and weak.
The amplitude of an analog signal is sampled at uniformed intervals, each sample is then quantized to the nearest value within a set range of digital steps.
In a PCM stream, the amplitude of the analog signal is sampled regularly at uniform intervals, and each sample is quantized to the nearest value within a range of digital steps. Bit depth refers to the number of possible digital values that can be used to represent each sample. Karlheinz Brandenburg , a professor at the Fraunhofer Institute was one of the lead developers of the MP3. By the late s, the MP3 was almost ready but still having issues dealing with the human voice.
Initially, MP3 compression absolutely destroyed the track leading to hundreds of revisions to get it right. The MP3 format still widely divides opinion but whether you think it saved the industry or ruined it, it certainly had a huge effect on it. There were some seminal moments in the history of MP3: the release of the Winamp media player for Windows in was huge.
The big change was that people could now have hundreds of songs on their computer without filling up their entire hard drive. In came Napster, the most infamous of the peer2peer sharing platforms which would be caught up in endless legal battles with most of the record industry. Most mobile phones now have enough storage for all the music you can handle. It is an accurate, lossless format, the quality remains the same as the original recording. Files are easy to edit and process with user-friendly software from freeware to professional applications.
Despite several advantages and disadvantages for each, the argument over MP3 or WAV will always come down to quality vs. If you are an artist hoping to release a single, most online music stores require the WAV format. Imagine paying a mastering engineer to add the final polish then handing over an MP3 to work from. We use Google Analytics to gather statistics about user activity.
