Audacity can record and playback audio on your Windows PC using one of the following three alternative interfaces:

• MME

• Windows DirectSound

• Windows WASAPI

ASIO (Audio Stream Input / Output) is an additional proprietary interface to record and playback audio in Microsoft Windows. ASIO bypasses the Windows audio mixing components to provide lower latency direct communication between computer audio software and hardware. Most audio recording interfaces manufacturers provide a driver to support ASIO.

• ASIO supports 24-bit sampling which is only otherwise available using Windows WASAPI or WDM-KS (Windows Driver Model Kernel Streaming). 24-bit sampling allows greater dynamic range, lower theoretical noise floor and greater resolution at lower audible volumes.

• An unmixed ASIO output is "bit identical" to the original source.

• Multiple physical input and output channels of the hardware are accessed over one single device.

Windows DirectSound interface protocol support multi-channel recording on some sound devices, but not the very low latencies that are possible on ASIO.

• Use case: spoken word with music in the background

• Moving clips & Sync lock

• Splitting a recording into several tracks

What are the main uses for Macros?

Macros in Audacity can be used for:

• Batch processing: Apply one or more effects to multiple audio files and export the processed audio into a new file.

  To use this select the Apply Macro to: Files... button in the Macros Palette or the Manage Macros dialog.

  For more detail on batch processing please see this page.

• Effects automation: where the selected audio in the track or tracks in the current project is subjected to the same prescribed sequence of effects, and optionally, a file exported from the entire audio.

• Effect presets: where selected, commonly used, effects are stored with your preferred settings for quick re-use.

How to access Macros

You can manage and apply Macros using the Tools Menu:

• Tools > Macros... to manage Macros: to create, edit and test them

• Tools > Apply Macro > Palette... for a toolbox of Macros

• Tools > Apply Macro > named Macro to apply one named Macro

There are some examples of Macros and tips on using them.

Manage Macros

Use Tools > Macros... if you need to create a new Macro or to edit an existing Macro.

Macros Palette dialog

Use the Shrink button to show a reduced Macros Palette dialog which lists the existing Macros.

This dialog is also available directly via Tools > Apply Macro > Palette...

Apply Macro to

Both the Manage Macros dialog and the Macro Palette dialog have Apply Macro to buttons:

• Project applies the selected Macro to the current project.

• Files... applies the selected Macro to selected external audio files that are in a single directory.

For more details see the Macros Palette page.

Macro Command Parameters

Commands that call Effects, Generators, Analyzers or Tools, use the same familiar graphical interface (GUI) as appears when they are used from the normal top level menus.

Many of the other commands provide a simple GUI comprised of checkboxes and text entry boxes. Typical examples can be seen in the Scriptables I and Scriptables II menus.

Please see Manage Macros for more details.

Sharing a Macro

You can export a Macro as a TXT file using the Export button in Manage Macros and send it to another user, or copy it to another computer for use there

You can import another user's Macro, or a copied macro of your own, into your Macros folder by using the Import button in Manage Macros.

Where Macros are stored

Each Macro is automatically saved as a separate text file with TXT extension in the Macros folder in Audacity's folder for application data:

• Windows: Users\<username>\AppData\Roaming\audacity\Macros

• Mac: ~/Library/Application Support/audacity/Macros

• Linux: ~/.audacity-data/Macros

Macros Examples

See the Macros Examples page for examples of using Macros
