Why Can I Only Burn 80 Minutes of Music to a CD if My MP3s Take Up Less Than 700MB of Space?

Posted on

When burning a CD, you possibly can both burn it as a information disc or an audio CD. An information CD can maintain up to 700 MB, whereas an audio CD can maintain 80 minutes of sound. When you have 200 MB of MP3 recordsdata that add up to three hours of music, you possibly can nonetheless solely burn 80 minutes to the disc. Why is that?

What Occurs When You Burn a Knowledge CD

On the time of burning, you select to burn both a information CD or audio CD. Your disc burning program burns the disc in a completely different format relying on the choice you select.

Knowledge CDs are easy to perceive. If you burn a information CD containing MP3s or another sort of file, your pc creates a disc containing these recordsdata. The recordsdata on the disc are the identical dimension as they’re in your pc. So, if you’ve gotten 200 MB of MP3s you need to burn to a 700 MB disc, you possibly can place the MP3 recordsdata and up to 500 MB of different information recordsdata on the disc.

Why Burning an Audio CD is Totally different

Burning an audio CD is completely different. Audio CDs should not the identical factor as information CDs, and they don’t comprise MP3 recordsdata.

An audio CD comprises audio information in CDDA (Compact Disc Digital Audio) format. That is uncompressed audio information, and it requires a lot extra space than MP3 recordsdata, AAC recordsdata, or another sort of compressed audio file. A minute of CDDA audio at all times takes up the identical quantity of area on the disc, which is why you possibly can solely burn a most quantity of minutes to a disc. Even if the songs  you’re burning are in MP3 format, they’ve to be transformed to the bigger CDDA format if you need the disc to work in a common CD participant.

It goes the opposite path, too. Audio CDs you purchase in shops can solely have a most of about 80 minutes of sound, however if you rip an album to MP3 or AAC format, it should use lower than 700 MB of cupboard space in your PC. So as to convert CDDA to MP3, your pc makes use of a “lossy” compression course of, the place some information is thrown out. In any other case, your ripped music assortment would take up an terrible lot of area!

Burning MP3s to Audio CDs Isn’t Preferrred

If you happen to burn an MP3 to an audio CD, the MP3s will develop to take up the identical quantity of area as the unique audio information. Nonetheless, the ensuing disc may have inferior audio high quality when put next to the unique audio CD.

If you rip music from a CD to an MP3 file or AAC file, you’re not getting all the unique audio information. Some of the information is discarded to make sure the MP3s have a small file dimension. The ensuing MP3 recordsdata gained’t essentially sound pretty much as good as the unique disc. How good they’ll sound is determined by the encoder you employ and its bitrate settings. Your headphones and audio system are additionally a issue: It can be simpler to inform the distinction with higher-quality, dearer headphones.

This is the reason audio geeks like lossless codecs like FLAC, which give some compression however hold all the unique audio information. If you happen to burn lossless recordsdata like FLAC to a disc, you’ll have an audio CD with sound high quality good as the unique.

If you burn lossy recordsdata like MP3s to an audio CD, the MP3s shall be transformed to CDDA audio, which takes up extra space on disc. However all of the audio information that was discarded when the MP3s have been created can’t be restored.

In fact, if you’re already fortunately listening to the MP3 recordsdata, an audio CD you burn from these recordsdata gained’t sound worse any worse than the MP3s. Nevertheless it gained’t essentially sound pretty much as good as the unique audio disc, both.

Some Disc Gamers Help MP3 CDs

There’s a compromise accessible, too. Some CD gamers can learn each normal audio CDs and “MP3 CDs”.

An MP3 CD is strictly what it feels like. Quite than changing the MP3 recordsdata to CDDA whereas burning an audio CD, you burn the MP3 recordsdata to a information CD. The disc participant than reads the CD, hundreds the MP3 recordsdata, and performs them identical to a pc would.

To search out out if your disc participant helps MP3 CDs, search for an “MP3” emblem on it. You can too learn its instruction handbook or test its specs, and you must see MP3 help listed if it has it.

To create an MP3 CD, you merely burn a information disc and fill it with up to 700 MB of audio recordsdata. It’s your decision to manage the MP3s into folders in order that they’re simpler to navigate by means of in your disc participant. Some purposes, like iTunes, have an “MP3 CD” possibility, however you possibly can obtain the identical factor by burning the MP3 recordsdata to a information disc with any disc-burning instrument.

These CDs gained’t work on any previous CD participant, so this isn’t essentially the most appropriate answer. However, if you employ a CD participant that helps MP3 CDs—possibly your automobile stereo does, for instance—you possibly can burn MP3 CDs as a substitute of audio CDs to match extra music on a disc.
