dBpoweramp: Wave Encoder

Wave is a container format, that is it can contain many types of audio, most commonly uncompressed (PCM), or compressed audio using one of the many ACM codecs installed in to Windows.

Supported by this Codec
  • Encoding: Yes   [.wav]
  • Multi-processor Encoding: Yes   (with dBpoweramp reference)
  • Decoding: Yes   [.wav, .wave]
  • ID Tag Reading: Yes   [Wave LIST & ID3 Tags]
  • ID Tag Writing: Yes   [Wave LIST & ID3 Tags]
  • Unicode Tagging: Yes with ID3
  • Supports Album Art: Yes with ID3
  • Gapless Encoding & Decoding: Yes
  • Explorer Audio Popup Information: Yes
  • Unicode Filenames: Yes

Compression Options

Uncompressed is a standard PCM wave file, because uncompressed is much larger than mp3 (10x) and larger than lossless files (2x). Setting bits, channels and frequency to [as source] ensures the wave file matches the quality of the source.

Compressed, click Settings to choose from installed ACM codecs.

Wave-Mp3, creates a mp3 compressed wave file, using the high quality Lame encoder (dBpoweramp Reference required).

Codec Background

Wave was developed by Microsoft and IBM, using the RIFF 'chunk' container format. Majority of Wave files are uncompressed PCM, however can also store compressed audio (requires a system ACM codecs to decode).

ID Tag Details

Wave files can store limited (choice of fields) ID Tags in a Wave LIST chunk, or a full range id ID Tags in an 'id3 ' chunk (which is an id3v2 tag). By default both types of tags are written for maximum compatibility. Not all programs can read these chunks.

Advanced Options

dBpoweramp Configuration offers advanced options for this codec (dBpoweramp Control Center >> Audio Codecs 'List / Options'):

Wave ID Tagging

This section allows for configuration of LIST tags, to set optimum compatibility with decoding program. Padding can be used so that when ID Tags are edited the whole file does not need rewriting.

Wave Encoder

Write Extensible Header: Microsoft introduced an extended wave header called Extensible, the idea is to offer more fields for high definition audio. The only fly-in-the-ointment is compatibility of programs and the extensible header. This option can switch to never write an extensible header.

Command Line

dBpoweramp Reference allows compressions from the command-line, commands specific to this codec:

-bits="16", or "float" (non supplied uses [as source])
-freq="44100" (non supplied uses [as source])
-channels="2" (non supplied uses [as source]) "1" to "9"

Example: "c:\program files\illustrate\dBpoweramp\coreconverter.exe" -infile="c:\afile.mp3" -outfile="c:\outfile.wav" -convert_to="Wave" -bits="24"


Encoding:  compress and write audio track,
Decoding:  uncompress and read the track,
ID Tags:  meta data such as artist & album are embedded inside the audio file,
Lossless:  compression without audio quality loss,
Lossy:  audio quality is sacrificed (how much depends on bitrate and codec used) to achieve smaller files,
Gapless:  allows the decoder to decode audio stream without gaps (silence),
Explorer Audio Popup:  a dBpoweramp function, hold the mouse over a supported audio file and details contained are displayed,
Multi-processor Encoding:  for multi core processors multiple files can be compressed at once fully using all cores.
Command Line: 
text interface, where commands are typed (start >> run >> cmd  to get to the command line)
