Utility Codecs

Utility Codecs do not compress or read audio, but rather perform useful action. Firstly they have to be enabled so that they appear in dBpoweramp, from dBpoweramp Control Centre select >> Configure then choose Converter tag and check Enable Utility Codecs.

By using Batch Converter whole folders of tracks can be processed in one go, a word of warning, test the actions on a few files to make sure everything is setup correctly before letting loose on all the files.

The following Utility Codecs are available:

[Arrange Audio]

Arrange Audio is a utility codec that arranges audio tracks, these files are renamed or moved using information from the ID Tags. Your whole audio collection can be arranged into a uniform file and folder names.

Use the program dBpoweramp Batch Converter to select whole folders and sub-folders of files in one click for arranging. Be careful using Arrange Audio, as once renamed, audio files cannot be reverted to the original filenames, test on a small group of files first.

A root path is set, this can be a drive such as c:\ or a drive and folder ie c:\Music Folder.

Next is Arrangement, this is added to the root path, dynamic values (such as [artist] filled with the value from ID Tag). Do no enter any extension as the extension from the original file is preserved.

Used arrangement values (such as [artist]) rely on this value being present in the ID Tag, other values such a [encoder] are taken from the file. See Naming Details of the available tag elements

[Audio Info]

Extracts audio details and presents them as a list, or a tab delimitated table (for pasting into a spreadsheet, such as Excel). Designed to extract details from 100's if not 1000's of files in one go, use with dBpoweramp Batch Converter to select all audio files with one click. The information extracted relates to the audio properties (Sample Count, bit rate, etc) and ID Tags.

Extensive Audio Information when checked extracts extra technical fields as well as ID Tags.

Tab Separated Table when checked results of all files are collated in a tab delimiter table, when results are displayed in notepad it will look jumbled, paste into a spreadsheet to view correctly.

[Calculate Audio CRC]

Calculates the CRC value, or MD5 hash value of decoded source audio data only (from input file). Normally audio files have headers (such as wave files) and ID Tags, using this utility will generate the CRC value of the decoded audio data only. Not overly useful with lossy audio files (as very slight changes from the decoder generate different crc values), but very useful with Lossless codecs (Illustrate use [Calculate Audio CRC] when developing lossless codecs to check a lossless is working without error).

[Channel Split]

Splits channels from multi channel audio files into separate files. Encode To specifies the encoder to encode the extracted channels with.

Split File Naming gives the choice of how the split channel files should be named. The channel identifier is added to the end of the source filename, for example if the source file was 'sine sweep.mp3' the resulting files would be 'sine sweep_Ch1.wav' and 'sine sweep_Ch2.wav'. There is also an option to write out more descriptive names such as _Left _Center _Back Left, etc.

[ID Tag Update]

A utility codec which updates ID Tags. Why update tags?, perhaps all your mp3 files have an old ID3v1 and you want ID3v2 tags, ID Tag Update will read all existing tags and write new tags to the file (old ones removed) using the tag creation settings from dBpoweramp Configuration.

In addition to updating ID Tags, manipulations can be made whilst they are updated:

  Map copy a tag to another name, for example copy Artist to Album Artist. The original tag value is left untouched

  Additions: add new tags, for example it is possible to add a Comment as (c) Your Company.

  Deletions it is possible to remove All Tags, All Except, or delete a Single Tag


Album Art

Art can be exported, or imported from Folder.jpg

Specify a Maximum Art Size, or a maximum byte size for the Art.

Force embedded Album Art to JPEG from PNG for compatibility reasons.


When using meta data sources such as freedb there is little consistency between discs, this option allows character capitalization to be set. The Smart Capitalization option would create a tag 'A tag and Another' from 'A TAG AND ANOTHER'

Rule Based Manipulation

Offers advanced programmable actions on tags, such as:

   IF Genre=[anyvalue] set if Genre if contains a value
   SET Genre=Rock

   IF Genre= set genre if contains nothing
   SET Genre=Unknown

   IF Genre=Alt Rock all genres
   SET Genre=Rock

   IF Album=Christmas example showing setting a different tag
   SET Genre=Christmas

   IF Artist=The Beatles fixed changes
   SET Artist=Beatles, the

   IF Album Artist=The Beatles
   SET Album Artist=Beatles, the

   IFCONTAINS Album=Best of for generic albums, add the artist name
   SET Album=[album], [artist]

   IF Album Artist= set album artist if empty (from artist)
   SET Album Artist=[artist]

   IF Artist= if no artist then set to unknown
   SET Artist=Unknown Artist

Word / Character Replacement

Allows individual characters or whole words to be substituted with another character or word, or to be deleted when no substitution is specified.

Externally Script Tags allows: an external script to alter ID Tags, full scripting details

Multiple Artist To 'Artist1; Artist2' dBpoweramp follows standards set by tagging formats when it comes to handling multiple artists (each tag type is different). A problem arises when another program does not follow these rules, by not following the rules correctly said program might not read the 2nd Artist, or only the 2nd Artist. This option forces all artists into one artist, separated by '; '. Be aware, programs which follow the tagging conventions correctly will not detect 2 separate artists once forced onto one line.

Multiple Artist From 'Artist1; Artist2' detects artists separated by '; ' and sets them internally to multiple artists correctly stored as defined by the tagging format.

Multiple Artists to '[title] (feat. Artist2)' takes the 2nd artist out of the artist field and puts it into the title, ie 'Title (feat. Artist 2)'

Multiple Artists from '[title] (feat. Artist2)' detects a 2nd artist in the title field and moves it to the artist field

The order of manipulations carried out are: Map, Deletions, Manipulation, Additions.

[Length Split]

Splits a larger file into smaller "chunks", for example a 10 minute audio book could be split into ten one minute files. When splitting the new split filenames are {Original Filename}-001, -002, -003 for the first, second and third respective files.

Encode To specifies the encoder the shorter files should be encoded with.

Split Every sets the length to split.

When Split Go Back: can be useful with audio books so the new split file contains a portion from the end of the previous split file, when listening to a narrative it is good to get the last sentence again.



The purpose of this utility codec is to calculate and ID Tag ReplayGain values to already existing audio tracks. ReplayGain ID Tags contain volume adjustment information which a player can use to alter the volume of a track to make it the same loudness as other tracks.

There are 2 types of gain values, a TrackGain which is calculated solely for that track, or AlbumGain which takes all the tracks on an album and calculates relative to one another, so that an intentionally quiet track on an album, stays quieter. The ability to store Replay Gain tags depends upon audio format used and ID Tagging method.

To add ReplayGain values whilst compressing new audio tracks use the Replay Gain DSP effect instead.

The Write option specifies which tags are written, including iTunes compatible tags.

The advanced page enables fine tuning of the options, from the calculation method (EBU R128 is recommended), to the reference loudness (-18LUFS).

Albums can be defined by the album ID tag, or if the tracks do not have ID Tags, group all tracks in the same folder as an album.

It is also possible to disable the clip prevention (the player should have clip prevention if disabled).


[Tag From Filename]

Splits a filename and creates ID Tags from the filename and path, for audio files which have no ID Tags but constant filenames.

Tag Recognition this is where the format of the filenames is entered, for example audio files are in the format:

/A Folder/4 Madonna - Holiday.mp3
/A Folder/6 Eminem - My Name Is.mp3

Tag Recognition would be set to: [track] [artist] - [title]

Another example:

/SomeFolder/ArtistName/AlbumName/TrackNumber Artist - Title.mp3 Tag recognition would be set to:

/[artist]/[album]/[track] [artist] - [title]

To recognize [ and ] as fixed string enter [[ ]], for example track number is surrounded by [], example: [12] so recognition would be [[[track]]]

dBpoweramp has a set of standard tag elements, such as [artist], but any tag value can be specified in [ ] brackets, by using standard tag elements ensures they are mapped to the correct locations.
