No, usually MP3 files are much smaller than wave files, because they use compression to reduce the size.
Wav files are uncompressed files so they take up more space than mp3s. They require special tools to open and play and will not sink with most mp3 players.
MP3 files opened with Audacity will be converted to a non-compressed Wave files format for editing. To save the file back as an MP3, you will need to install a 3rd party MP3 codec such as the LAME MP3 encoder.
MP3 and Wave files are two different audio file formats. If you open an MP3 file into a program such as Audacity or Wavelab, the program converts it to a Wave file to edit it.
MP3 files are smaller so there faster to download
WAV files have better audio quality but are larger in file size compared to MP3 files.
AAC files are usually smaller with better sound quality than an MP3 file.
It does play wave files and mp3, but only play mp3 in tracks form not any mp3 file.
An mp3 takes less memory than a wave file because it is usually compressed.
Yes, normally. Wav from CD (which is actually "Red Book Audio" but it rips to .wav) is 1411 kb/s. MP3 (at largest size) is 320 kb/s, and most MP3s are smaller than that. Wav in most cases is 5-10 trimes larger than MP3s.
Sony boomboxes play MP3 files as well as WMA files but can also cost a fair bit more than other boomboxes.
A Zune is not an audio format like an mp3, it is a music/video player designed by Microsoft. It plays mp3 audio files as well as Microsoft's mp3 alternative, wma audio files.
A Sony MP3 CD is a disk that stores a limited amount of music files on it. A Sony MP3 player is more of an electronic device that has a larger capacity to store music files on it. It is also much more portable and convenient to carry and use to listen to music.
