They had the advantage of sitting next to a video signal the size of Albania, so designing a higher quality sound signal was trivial by comparison. They use very slightly higher sample rate because they have a lot of elbow room. Audio CD is 44100, 16-bit, Stereo too, but there are no options. You just have to know.Īudacity default WAV export is 44100, 16-bit Stereo or Mono depending on the show. The different qualities are not called out like that. An ALAC or FLAC is about 60% the size of the uncompressed WAV. I believe iTunes can convert a WAV file to ALAC. ITunes supports ALAC, which is lossless compression similar to FLAC. Multiply that by 60 and you get about 10MB per minute Or for a CD (or equivalent WAV) you can calculate a bitrate of 1411kbps (kilo_bits_ per second). And, it has a sample rate of 44.1kHz so there are 44,100 samples per second, for a total of 176,400 bytes per second. If you know that information, and if you know there are 8-bits in a byte, you can calculate file size.įor example, a “CD quality” WAV file is 16-bit stereo, so that’s 4 bytes per sample. The size of a WAV file is simply related to the playing time, the bit depth (the number of bits per sample), the sample rate (the number of samples per second) and the number of channels. wav file it will be just as large as any other 3 min song that you add to I-Tunes as a.
wav while you are working on it and if you export it as a. Most “effects” can’t be done without decompressing, and you can’t do mixing or crossfading without first decompressing.ĭoes Audacity change the file to a. It doesn’t de-compress/re-compress, and since it’s working directly on smaller-compressed files it’s very fast. If you are doing “simple” editing, such as cutting/splicing or volume changes, try MP3DirectCut. Made some changes and now I want to export it.
