dBpoweramp Opus Help

dBpoweramp Opus Codec
Opus is a lossy audio codec, designed by the Internet Engineering Task Force. It is a modern codec suited well to streaming (low latency).
Supported by this Codec

- Encoding: Yes [.opus]
- Multi-processor Encoding: Yes (with dBpoweramp reference)
- Decoding: Yes [.opus]
- ID Tag Reading: Yes [Vorbis Comments]
- ID Tag Writing: Yes [Vorbis Comments]
- Unicode Tagging: Yes
- Supports Album Art: Yes
- Gapless Encoding & Decoding: Yes

Compression Options

Opus only has one option, that is the bitrate used to encode.

Advanced Options

dBpoweramp Configuration offers advanced options for this codec (dBpoweramp Control Centre >> Codecs >> Advanced Options):

> Decoder Options

> > Output can set either 16 bit, or 32 bit floating point

> > Sample Rate, as Opus internally stores all samples as 48KHz this option controls how to decode audio.

Command Line

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

> -bitrate [level] set encoding bitrate

> Example: "c:\program files\illustrate\dBpoweramp\coreconverter.exe" -infile="c:\afile.wav" -outfile="c:\outfile.opus" -convert_to="Opus" -bitrate 128

Terminology

> Encoding: compress and write an audio file,
> Decoding: uncompress, or read an audio file,
> 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 dual processor, or multi core processors multiple files can be compressed at once fully using both (or more) CPUs.
> Command Line: text interface, where commands are typed (start >> run >> cmd to get to the command line)
