To build this source code, simply type:
% make
If this does not work, or if you want to change the default configuration
(e.g., to compile for a fixed-point architecture), simply edit the options
in the Makefile.
An up-to-date implementation conforming to this standard is available in a
Git repository at https://gitlab.xiph.org/xiph/opus.git or on a website at:
https://opus-codec.org/
However, although that implementation is expected to remain conformant
with the standard, it is the code in this RFC that shall remain normative.
To build from the git repository instead of using this RFC, follow these
steps:
1) Clone the repository (latest implementation of this standard at the time
of publication)
% git clone https://gitlab.xiph.org/xiph/opus.git
% cd opus
2) Compile
% ./autogen.sh
% ./configure
% make
Once you have compiled the codec, there will be a opus_demo executable in
the top directory.
Usage: opus_demo [-e] <application> <sampling rate (Hz)> <channels (1/2)>
<bits per second> [options] <input> <output>
opus_demo -d <sampling rate (Hz)> <channels (1/2)> [options]
<input> <output>
mode: voip | audio | restricted-lowdelay
options:
-e : only runs the encoder (output the bit-stream)
-d : only runs the decoder (reads the bit-stream as input)
-cbr : enable constant bitrate; default: variable bitrate
-cvbr : enable constrained variable bitrate; default: unconstrained
-bandwidth <NB|MB|WB|SWB|FB> : audio bandwidth (from narrowband to fullband);
default: sampling rate
-framesize <2.5|5|10|20|40|60> : frame size in ms; default: 20
-max_payload <bytes> : maximum payload size in bytes, default: 1024
-complexity <comp> : complexity, 0 (lowest) ... 10 (highest); default: 10
-inbandfec : enable SILK inband FEC
-forcemono : force mono encoding, even for stereo input
-dtx : enable SILK DTX
-loss <perc> : simulate packet loss, in percent (0-100); default: 0
input and output are little endian signed 16-bit PCM files or opus bitstreams
with simple opus_demo proprietary framing.

- Check minimum width of bands
- Revisit energy resolution based on the bit-rate
- Revisit static bit allocation (as a function of frame size and channels)
- Dynamic adjustment of energy quantisation
- Psychacoustics
* Error shaping within each band
* Decisions on the rate
- Intensity stereo decisions
- Dynamic (intra-frame) bit allocation
- Joint encoding of stereo energy
- Encode band shape (or just tilt)?
- Make energy encoding more robust to losses?
Misc:
Detect uint decoding and flag them in the decoder directly
If we attempt to write too many bits on the encoder side, set a flag instead of
aborting
Save "raw bytes" at the end of the stream

add two sig values and that the first stages of the MDCT don't cause an overflow.
The most constraining is the ARM_ASM comb filter where we shift left by one
and then add two values. Because of that, we use 2^29-1. SIG_SAT must be large
enough to fit a full-scale high-freq tone through the prefilter and comb filter,
