When burning a CD, you have the right to either burn it together a data bowl or one audio CD. A data CD can hold up to 700 MB, if an audio CD can hold 80 minutes of sound. If you have 200 MB that MP3 documents that add up come three hours of music, you can still only burn 80 minutes to the disc. Why is that?


What Happens when You Burn a Data CD

*

At the moment of burning, you pick to burn one of two people a data CD or audio CD. Your disc burning regime burns the key in a various format depending upon the alternative you choose.

Data CDs are an easy to understand. Once you burn a data CD include MP3s or any other form of file, your computer creates a disc include those files. The documents on the disc space the very same size as they are on her computer. So, if you have actually 200 MB the MP3s you want to burn to a 700 MB disc, you can place the MP3 files and up come 500 MB of various other data records on the disc.

Why burn an Audio CD is Different

Burning an audio CD is different. Audio CDs space not the very same thing as data CDs, and also they execute not contain MP3 files.

An audio CD consists of audio data in CDDA (Compact disc Digital Audio) format. This is uncompressed audio data, and it requires a lot much more space than MP3 files, AAC files, or any other type of compressed audio file. A minute that CDDA audio always takes increase the same amount of an are on the disc, which is why you deserve to only burn a maximum variety of minutes to a disc. Even if the song you’re burning are in MP3 format, they have to be converted to the larger CDDA format if you want the bowl to work in a regular CD player.

It walk the various other direction, too. Audio CDs you buy in stores have the right to only have a best of around 80 minutes of sound, but if girlfriend rip one album come MP3 or AAC format, it will use less than 700 MB that storage an are on her PC. In bespeak to convert CDDA to MP3, your computer system uses a “lossy” compression process, whereby some data is thrown out. Otherwise, your ripped music collection would take it up an awful the majority of space!

Burning MP3s to Audio CDs Isn’t Ideal

If you burn an MP3 to an audio CD, the MP3s will broaden to take up the very same amount of space as the original audio data. However, the result disc will have actually inferior audio top quality when contrasted to the initial audio CD.

When friend rip music native a CD to an MP3 document or AAC file, you’re not obtaining all the initial audio data. Few of the data is discarded come ensure the MP3s have a small paper size. The resulting MP3 documents won’t have to sound as an excellent as the initial disc. How great they’ll sound relies on the encoder girlfriend use and its bitrate settings. Your headphones and speakers are also a factor: that will be much easier to tell the difference with higher-quality, an ext expensive headphones.

This is why audio geeks favor lossless styles like FLAC, which carry out some compression yet keep every the original audio data. If girlfriend burn lossless records like FLAC to a disc, you’ll have an audio CD with sound quality good as the original.

When you burn lossy files like MP3s come an audio CD, the MP3s will be convert to CDDA audio, i beg your pardon takes up more space ~ above disc. But all the audio data the was discarded when the MP3s were developed can’t it is in restored.

Of course, if you’re currently happily listening come the MP3 files, an audio CD friend burn from those records won’t sound worse any kind of worse 보다 the MP3s. But it won’t have to sound as an excellent as the original audio disc, either.

Some bowl Players assistance MP3 CDs

There’s a weaken available, too. Some CD players have the right to read both standard audio CDs and also “MP3 CDs”.


An MP3 CD is specifically what it sounds like. Rather than converting the MP3 records to CDDA while burn an audio CD, you burn the MP3 files to a data CD. The bowl player then reads the CD, lots the MP3 files, and plays them just like a computer system would.

To discover out if her disc player support MP3 CDs, look for an “MP3” logo on it. Friend can also read the instruction hands-on or examine its specifications, and you should see MP3 support listed if it has it.

To produce an MP3 CD, you simply burn a data disc and also fill it v up come 700 MB of audio files. You might want to organize the MP3s into folders so they’re simpler to navigate v on your disc player. Part applications, favor iTunes, have an “MP3 CD” option, however you can accomplish the exact same thing by burning the MP3 records to a data disc with any disc-burning tool.

These CDs won’t work on any old CD player, so this isn’t the most compatible solution. But, if you use a CD player that supports MP3 CDs—maybe your vehicle stereo does, for example—you can burn MP3 CDs instead of audio CDs to fit more music ~ above a disc.
