How to Upload Sounds Into a File

Post a Comment

This folio is about importing sound files into Audacity (like WAV or MP3) that other applications on the reckoner tin can play.

Alert Audacity projects cannot be opened using the File > Import > Audio... command, you will get an error bulletin.

If you take already saved your audio as an Audacity Project, apply or to open the <my_project_name>.aup3 .

Audio File Formats Supported past Audacity

The audio formats importable by Audacity with the command, as shipped are:

Uncompressed audio formats

For uncompressed audio: most WAV and AIFF files including all PCM variants can exist imported into Brazenness

Compressed audio formats

Compressed audio: MP3 , Ogg Vorbis , FLAC and MP2 tin can be imported into Brazenness.

FFmpeg for other importable audio formats

Y'all can install the optional FFmpeg library to import a much larger range of audio formats including AC3, AMR(NB), M4A, MP4 and WMA (if the files are not DRM-protected to work only in item software).

FFmpeg will also import audio from most video files or DVDs that are non DRM-protected.

Older uncompressed file types such as WAV with U-Constabulary or IMA ADPCM encoding are generally supported provided they comprise correctly formatted header data.

  • If files exercise not have header data (such as RAW or Vox ADPCM) or accept non-standard header information, you can unremarkably import them using .
  • WAV files from portable recorders may contain proprietary compressed audio. These should not be imported as Raw Data, but by installing the FFmpeg library.
  • LOF files (lists of files) are besides supported if the list is correctly formatted and contains supported files.
Tip When importing an MP3 audio file you may run across the post-obit error message:
Alert Import Failed

This is likely to be caused past a malformed MP3.

Workarounds for this can be found at Opening malformed MP3 files.

Iii Ways to Import Audio

No matter which method y'all employ to bring an audio file into Brazenness, the file is e'er imported into a saved or unsaved Audacity projection. The imported file ever appears in a new runway in that project.

ane.

If you select the control, and so choose one or more audio files, Audacity volition import the selected file(south) into the existing projection. This is useful to bring the content of ane or more than audio files into a project that already contains audio (for example, to mix several audio files together).

ii. (Open Recent on Mac)

This command imports a single file from a list of the 12 nigh recently imported files or recently saved projects. The file opens in a new window exactly every bit .

iii. Drag and drop

Advice Note that you cannot employ drag and drib an AUP3 project into an open Audacity Projection window. To open up Audacity projects - use File > Open up... to open projects.
  • On Windows and Mac:
    • Drag and drop i or more sound files into an open Brazenness project window: this is equivalent to .
    • Drag and drib one or more sound files onto the Audacity icon: this is equivalent to .
  • On Linux:
    • Drag and drop files into an open Audacity Projection window: this is equivalent to .
    • Drag and drop 1 or more audio files onto the Brazenness icon: but the first file will open. More than one file dragged and dropped onto the icon will do the same as the command for the first file, merely the other files will generate an error message saying that Audacity is already running.

Metadata

Audio files can bear descriptive information in a metadata container, this allows information such as the title, artist, album, runway number, and other information well-nigh the file to exist stored in the audio file itself.

Each fourth dimension an audio file is imported into the aforementioned projection window, the metadata tags for that file supervene upon the previously stored metadata for the project. And so if the last imported file has no metadata, the projection will no longer have any stored metadata. Using one of the above methods that imports each file into its ain projection window will ensure each file's metadata is stored.

This bill of fare (called "Format" on Mac) contains a listing of different file types.

File type drop-down menu W10 3-0-2.png

Choosing a item file type in the menu performs two functions.

  • The file type selection filters the listing of files in the window past restricting it to files of that type.
  • The file type selection determines which importer attempts the file first when using the Open up or Import Audio dialogs. For instance, a WAV file could be imported past Brazenness's native WAV importer or by the optional FFmpeg library if this was installed.
    • Additionally, rules for the order in which dissimilar importers endeavour files of particular types tin can be created at Extended Import Preferences with an option to over-ride the Open and Import Audio file type choice. See Import Filtering and Importer Order for more than details.
  • Import tin can as well exist used to import a list of audio files by selecting List of Files in basic text format. Run into LOF Files for more details.

Importing audio from CDs

Audacity does not comprise any function for importing (ripping) audio from CDs. This can, still, be achieved by using other applications to extract the information into a file format Audacity does support.

See the tutorial How to import CDs.

Sample Rate and Sample Format of imported files

Audacity always imports files at their original sample rate , every bit displayed in the Track Information Area of the Track Control Panel.

When importing a file into an empty projection window (as always happens when using as described below), the Project Rate control in Pick Toolbar changes if necessary to reverberate the rate of the file. The Project Rate determines the sample rate a file volition be exported at, then no farther aligning is needed to consign that file at its original rate. However, in one case there is already an audio rails of any origin in the project (either an imported file, a recording or generated audio), importing an audio file volition never change the project rate.

Generally, Audacity imports files at the sample format (bit depth) specified at Default Sample Format in Quality Preferences. This setting defaults to 32-bit float. Therefore by default an imported file volition evidence in the Track Control Panel as 32-bit float, fifty-fifty if its original fleck depth is lower. This is best for high-quality editing. Even if you lot choose a lower Default Sample Format than 32-bit bladder, Audacity will never downconvert a file that has a higher scrap depth, as shown in the post-obit table for WAV and AIFF imports using the standard uncompressed files importer.

Resolution of imported WAV and AIFF files using standard importer
Default Sample Format File chip depth Resolution imported at
sixteen 16 sixteen
16 24 32
xvi 32 32
24 16 24
24 24 32
24 32 32
32 (default) sixteen 32
32 (default) 24 32
32 (default) 32 32

OGG is unusual in that it will ever import at 16-flake resolution using the standard OGG Vorbis importer, irrespective of Default Sample Format. This is due to the pattern of the OGG codec. However OGG can be imported at 32-bit resolution using FFmpeg, as described at Using the file type dropdown menu.
