Audio formats to which Audacity exports using software toassign upc a with asp.net web,windows application Microsoft Office Official Website We discussed in th upc a for None e first chapter how Audacity can save files in many file formats. When you save a project, it is saved as an AUP, or Audacity Project, file with a corresponding folder with the same name as the project, which contains all of the additional project files. But when you export a file, everything is converted and then saved into one file.

Export file formats supported by Audacity without additional software are: AIFF (Apple) signed 16 bit PCM WAV (Windows) signed 16 bit PCM GSM 6.10 WAV (mobile) Ogg Vorbis files FLAC files MP2 files. Saving Projects and Exporting Podcasts Additional export UPC-A for None formats are available by installing simple plug-ins or libraries that add additional functionality to Audacity. These formats, and their associated plug-ins, are: MP3, with the LAME MP3 encoding library Various FFmpeg formats, such as, M4A (AAC), and WMA, are supported through the FFmpeg import or export library Various other uncompressed file formats, such as: AU, AVR, HTK, IFF, and so on. Podcast formats Podcasts can be in upc a for None any number of audio formats as long as someone can listen to it on their computer or handheld audio device. But, by far, the most common podcast format is MP3. This is a compressed file format.

Compressed formats mean that the quality of the recorded audio is lowered in order to make the file size smaller, but the lost quality won"t be noticeable by most people. Also, in this case, it exports an audio file into a single file that is easy to share with others. We"ll learn how to export in MP3 format, and discuss other formats that might be useful.

The term or audio file extension MP3 is short for MPEG-1 Audio Layer 3. At a very high level this is an audio compression standard used when exporting audio. The file sizes are small, and it is easy to send these files through e-mail, or post them on an Internet site for someone to download.

Compression means that all of the audio is combined and exported to a single file. The quality is reduced by using lower bitrates. For example, traditional music found on a CD is recorded at 1411.

2 kilobytes per second (kbps) and a high quality MP3 is saved at rates like 320 kbps. But MP3s could be saved as low as 8 kbps, which reduces the file size considerably depending on the sound quality you want..

Installing libraries Before you jump in Software UPCA and get ready to export your podcast to MP3, you"ll need to install a library that allows you to encode (or digitize) MP3 files. Due to software patents, Audacity can"t package these libraries with the program itself, so we"ll download and install manually. We"re going to use LAME, a high quality MP3 encoder licensed under the General Public License (GPL).

This means that it can be widely distributed with open source software projects like Audacity. Installation is easy, in that you just have three basic steps: download, extract, and save the files to the Audacity folder. So let"s do that.

2. Find the approp riate LAME file for your computer"s operating system, and then click on the link to download the compressed file. 3.

Once downloaded, double-click on the .dmg (for Mac computers) or .exe (for Windows) file to start the installation.

For Linux, there are multiple distributions available. Download and install the file, based on that version"s installation instructions. 4.

You will be prompted to save the library file, which is called: libmp3lame. dylib. You can save this anywhere on your computer, but we recommend that you place it in the Audacity folder on your computer so that you remember where to find it when prompted when you save your first MP3 file.
