Two Cases to Make Audio File Smaller. There are several ways to compress an audio file. But everything depends on the source file quality. If you have purchased or. Importing Audio Audacity Development Manual. This page is about importing audio files into Audacity like WAV or MP3 that other applications on the computer can play. If you have already saved your audio as an Audacity Project, use or to open the lt myprojectname. Do not attempt to open, import or manipulate any individual AU files. See Audacity Projects for more information. Contents. Audio File Formats Supported by Audacity. Sample Rate and Sample Format of imported files. Four Ways to Import Audio. Using the file type dropdown menu in the Open and Import Audio Dialogs. Importing Uncompressed Audio Files. Importing Compressed Audio Files. Importing audio from CDs. Audio File Formats Supported by Audacity. The audio formats importable by Audacity as shipped are. You can install the optional FFmpeg library to import a much larger range of audio formats including AC3, AMRNB, M4. A, MP4 and WMA if the files are not DRM protected to work only in particular software. FFmpeg will also import audio from most video files or DVDs that are not DRM protected. On Mac only, Audacity can import M4. A, MP4 and MOV files without FFmpeg. Older uncompressed file types such as WAV with U Law or IMA ADPCM encoding are generally supported provided they contain correctly formatted header information. If files do not have header information such as RAW or VOX ADPCM or have non standard header information, you can normally 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 also supported if the list is correctly formatted and contains supported files. Sample Rate and Sample Format of imported files. Audacity always imports files at their original sample rate, as displayed in the Track Information Area of the Track Control Panel. Rogue Element Rogue Rock Rarity. When importing a file into an empty project window as always happens when using as described below, the Project Rate control in Selection Toolbar changes if necessary to reflect the rate of the file. The Project Rate determines the sample rate a file will be exported at, so no further adjustment is needed to export that file at its original rate. However, once there is already an audio track of any origin in the project either an imported file, a recording or generated audio, importing an audio file will 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 3. Therefore by default an imported file will show in the Track Control Panel as 3. This is best for high quality editing. Even if you choose a lower Default Sample Format than 3. Audacity will never downconvert a file that has a higher bit depth, as shown in the following 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 bit depth. Resolution imported at. OGG is unusual in that it will always import at 1. OGG Vorbis importer, irrespective of Default Sample Format. This is due to the design of the OGG codec. However OGG can be imported at 3. FFmpeg, as described at Using the file type dropdown menu. Four Ways to Import Audio. No matter which method you use to bring an audio file into Audacity, the file is always imported into a saved or unsaved Audacity project. The imported file always appears in a new track in that project. If you select the command, then choose one or more audio files, Audacity will import the selected files into the existing project. This is useful to bring the content of one or more audio files into a project that already contains audio for example, to mix several audio files together. This command behaves differently according to whether the project window in which you use the Open command has ever contained tracks of any type. If the project contains or has ever contained tracks at some point in its history so that and are not empty, Open imports each file you select into its own new project window. For example, selecting three files would create three new project windows, each containing one of the files and each a separate project with its own history. This is handy if you want to apply different actions to different or even the same files and easily compare the results of each. If the project is empty and has never contained any tracks for example, you used to create a new, empty project or used to close an existing project, Open imports the first file into the empty project window, then imports each subsequent file into its own new project window. Nitti Font Family Able Game. As with the other three import methods, Open does not directly open your selected files. The imported audio data is converted into a large number of small files in AU audio format, preserving the current quality of the data. Conversion occurs even if you never explicitly save your work as an Audacity project. So to save your edits to an audio file for the computer you always have to choose an Export command from the File Menu, even if you want to overwrite the exact same file that you imported. Open Recent on Mac. This command imports a single file from a list of the 1. The file opens in a new window exactly as. Drag and drop. On Windows and Mac Drag and drop one or more audio files into an open Audacity project window this is equivalent to. Drag and drop one or more audio files onto the Audacity icon this is equivalent to. On Linux Drag and drop files into an open Audacity Project window this is equivalent to. Drag and drop one or more audio files onto the Audacity icon only 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, but the other files will generate an error message saying that Audacity is already running. Using the file type dropdown menu in the Open and Import Audio Dialogs. This menu called Format on Mac contains a list of different file types. Choosing a particular file type in the menu performs two functions. The file type choice filters the list of files in the window by restricting it to files of that type. The file type choice determines which importer attempts the file first when using the Open or Import Audio dialogs. For example, a WAV file could be imported by Audacitys native WAV importer or by the optional FFmpeg library if this was installed. Additionally, rules for the order in which different importers attempt files of particular types 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 details. Importing Uncompressed Audio Files. The two most common uncompressed file types you will encounter are WAV and AIFF. Underworld 1 French Rapidshare Files. Warning Dialog when Importing Uncompressed Audio Files. The first time you import an uncompressed audio file into Audacity, you will see this dialog. For each imported file, you can choose. Whether to copy the imported files data into the project or to read its data directly from the file, as described below. Whether to make your copy or read directly choice permanent and never show this warning again. Import Methods. Make a copy before editing safer This is the default setting. When this option is chosen, Audacity copies the imported files into the projects audio data.
