What is a ACD file?

ACD is an audio format used by an audio editing software. ACD file don’t store any actual audio data, but information about an audio project, including:

  • applied audio effects,
  • sample libraries used,
  • equalizer settings for each audio source,
  • audio file output parameters.
  • ACD files are created by MAGIC ACID software application.

Changing ACD extension to, for example, MP3 will not change ACD file’s format. In order to open an ACD file in MP3 Player, such file must be converted using an appropriate tool.

How to open ACD files

If you cannot open the ACD file on your computer - there may be several reasons. The first and most important reason (the most common) is the lack of a suitable software that supports ACD among those that are installed on your device.

A very simple way to solve this problem is to find and download the appropriate application. The first part of the task has already been done – the software supporting the ACD file can be found in the table. Now just download and install the appropriate application.

Possible problems with the ACD format files

The inability to open and operate the ACD file does not necessarily mean that you do not have an appropriate software installed on your computer. There may be other problems that also block our ability to operate the Sonic Foundry ACID Audio Format file. Below is a list of possible problems.

  • Corruption of a ACD file which is being opened
  • Incorrect links to the ACD file in registry entries.
  • Accidental deletion of the description of the ACD from the Windows registry
  • Incomplete installation of an application that supports the ACD format
  • The ACD file which is being opened is infected with an undesirable malware.
  • The computer does not have enough hardware resources to cope with the opening of the ACD file.
  • Drivers of equipment used by the computer to open a ACD file are out of date.

If you are sure that all of these reasons do not exist in your case (or have already been eliminated), the ACD file should operate with your programs without any problem. If the problem with the ACD file has not been solved, it may be due to the fact that in this case there is also another rare problem with the ACD file. In this case, the only you can do is to ask for assistance of a professional staff.

How to associate the file with an installed software?

If you want to associate a file with a new program (e.g. my-file.ACD) you have two ways to do it. The first and the easiest one is to right-click on the selected ACD file. From the drop-down menu select "Choose default program", then click "Browse" and find the desired program. The whole operation must be confirmed by clicking OK. The second and more difficult to do is associate the ACD file extension to the corresponding software in the Windows Registry.

Is there one way to open unknown files?

Many files contain only simple text data. It is possible that while opening unknown files (e.g. ACD) with a simple text editor like Windows Notepad will allow us to see some of the data encoded in the file. This method allows you to preview the contents of many files, but probably not in such a structure as a program dedicated to support them.
