Diálogo de exportación de archivo

The Export File dialog for export of single audio files is accessed from Archivo > Exportar... or File > Exportar selección.... This dialog lets you specify folder location, file name, format and encoding options for your exported file.

You can use Archivo > Exportación múltiple to export multiple audio files (basado en pistas de etiquetas o múltiples pistas de audio) en un proceso.

After pressing "Save" in the "Export File" dialog, the Editor de metadatos will appear (unless you have disabled it for the export step in the Preferencias de Importar/Exportar). Metadata Editor lets you enter embedded information in the file such as artist, year or genre.

Diálogo de exportación de archivo

• Nombre de archivo: Type the required file name. The correct file extensión - preceded by a period (dot) - will be added automatically to the end of the file name, according to the format selected in the "Save as type" list (see below). For example, typing "Walkin' After Midnight" (without quotes) as in the image above will produce a file "Walkin' After Midnight.mp3". For M4A and WMA formats (for which the librería opcional FFmpeg is required), you can add alternative extensions as specified in "formatos FFmpeg" abajo.

  Any other extensions can be added after a file name as required, but Audacity will display a warning that this isn't the normal extension for this file type, and that some applications might not play files with non-standard extensions.

• Botón opciones: This opens another dialog for making settings like calidad o codificación for formats with options. As an example, here are the Options dialogs para los formatos Sin compresión y MP3:

 :

Always select the "Save as type" before clicking the Options button.

• "Save as type" list: Click a link after the bullet point to view any available options and further details for that format.
  • Otros archivos sin compresión: includes all the formatos de audio sin compresión that Audacity can export, including 8-bit, 24-bit and 32-bit options. This menu item defaults however to WAV (Microsoft) signed 16-bit PCM.
  • AIFF (Apple) signed 16 bit PCM and WAV (Microsoft) signed 16 bit PCM: WAV and AIFF are uncompressed, sin pérdida formats which can be opened on either Windows or Mac computers. Choose WAV or AIFF 16-bit PCM whenever you want to burn your exported file to an CD de audio.
  • GSM 6.10 WAV (mobile): produces a mono WAV file encoded with the compressed, lossy GSM 6.10 códec as used in mobile telephones.
  • Archivos MP3: MP3 is a popular con compresión, con pérdida format producing much smaller files than WAV or AIFF, at the expense of some loss of quality.
    You must download the optional codificador LAME to export to MP3.
  • Archivos OGG Vorbis: Ogg Vorbis is the compressed, lossy Vorbis codec in an OGG container. Vorbis offers higher quality than MP3 for the same file size, and is useful for good quality small-sized mono files, but fewer applications can play the OGG format.
  • Archivos FLAC: FLAC is a compressed but lossless format, giving larger file sizes than MP3 and OGG.
  • Archivos MP2: MP2 is a compressed, lossy format similar to MP3, producing slightly larger files than MP3 for the same quality.
  • (programa externo): sends audio via the command-line to an external application either for processing or for encoding as a file. This is a method to export to an alternative MP3 encoder, or to a format not supported by Audacity.
  • FFmpeg formats: The following export types marked "(FFmpeg)" are listed in released builds of Audacity on Windows and Mac, and in other builds where FFmpeg is enabled. They will only function if you install la librería opcional FFmpeg.
    • Archivos M4A (AAC): Advanced Audio Coding is a compressed, lossy format used in Apple applications, generally achieving slightly better quality than MP3 for the same file size. By default, the exported file will be given an "m4a" extension. Optional permitted extensions: .mp4, .m4r (ringtone) and .3gp (mobile).
    • Archivos AC3: the common name used for the compressed, lossy format used in Dolby Digital.
    • Archivos AMR (banda angosta) o (banda ancha): the Adaptive Multi-Rate codec is a patented compression scheme optimized for speech, but also used for mobile telephone ringtones. The wide band variant uses higher bandwidth for higher quality. Note: AMR (wide band) export will not be available in release builds on Windows and Mac. On Linux, AMR support is unlikely to be available unless you compile FFmpeg yourself with AMR enabled. These restrictions are due to licensing issues.
    • Archivos WMA (versión 2): Windows Media Audio v2 is a compressed, lossy format developed by Microsoft. Optional permitted extensions: .asf or .wmv.
    • Exportación FFmpeg personalizada: Allows choice of the specific codec to use in the formats listed above, or to export to some additional formats not otherwise available. Note: not all formats and codecs are compatible, and some exports might result in zero-byte or invalid files if FFmpeg does not support the combination chosen.
      
      

File size and channel comparisons by export format

The following table gives typical achieved mono and stereo file sizes with different formats at default Audacity settings (that is, 44100 Hz frecuencia de muestreo and default tasa de bits or quality settings in the case of compressed formats). Where VBR compression is employed, the achieved size will vary depending on the content.

Some formats can be exported as multi-channel files containing more than two channels, if you enable this at "Use custom mix" in the Preferencias de Importar / Exportar. The final column in the table shows the maximum number of channels per exported file.

(1)	The practical file size limit is 2 GB in many player applications due to their interpretation of the file size header. This also applies to 24-bit and 32-bit files where those bit depths are valid.
(2)	On Windows only, there is a file size limit of 2 GB due to a limitation in the encoding library on that platform. This also applies to 24-bit files.
