CSOUND VERSION 6.18 RELEASE NOTES

Mainly a bug-fixing release.  Major new facility is MP3 (MPEG) audio
files are supported both for input and output in platforms where this is 
supported by libsndfile.

-- The Developers

## USER-LEVEL CHANGES

### New opcodes

- scanmap reads internal state of scanu

- elapsedcycles, elapsedtime, eventcycles, and eventtime. See under
  "bugs fied" for detials.

### New gen

### Orchestra

### Score

### Options

### Modified Opcodes and Gens

- fix midi list printing to stdout part of the list.

### Utilities


### Frontends


## Bugs Fixed

- Fixed bug where fixed-point phase computation (in oscil family) was
  incorrect resulting in slight freq deviations in very low freq cases.

- Fixed bug where freeing instr 0 caused memory issues in new
  compilations. Instr 0 is not freed until reset now.

- Fixed a bug where opcode directory search was crashing Csound if HOME
  variable not set.

- Fixed pol2rect array size setting.

- OSCsend, OSCsend_lo and OSClisten can now work with OSC messages
  carrying no payload (as per spec and manual).

- bug in sum fixed

- 'pitchamd' opcode causes segmentation fault (macOS) (#1599)

- fixed crash on channel setting with empty channel name

- bug in ftloadk fixed (#1611)

- qnan works even when compiled with fast arithmetic

- Fix the flanger opcode for sample-accurate mode, where the xdel input was
not being correctly offset.

- elapsedcycles, elapsedtime, eventcycles, and eventtime introducd as
  fixed versions of timek, times, timeinstk and timeinsts but return
  the correct values instead of being one cycle late.  This prserves
  backward compatability

# SYSTEM LEVEL CHANGES

### System Changes

-  Fix for issue #1613:
   Fixes the rtauhal module for all cases of multichannel output. Previously the
   module would not work correctly with some devices.

-  Csound now supports MP3 files for input and output through libsndfile (version 1.1.0 and higher).

### Translations

### API

### External Plugin Code

### Platform Specific

Bela:

Many changes to Bela csound.  See bela web site for details

MacOS:

- Universal build for x86_64 and arm64, backward compatible to MacOS 10.9
- Issue where the portaudio callback backend would fail to work in mono (e.g. laptop microphone) has been fixed.

WASM:

- fix sampleRate for single-thread worklet.

Good question. I think many bugs end up in people's pieces and we can't fix them anymore. They become the proverbial feature.

Hmm, any idea what was the oldest bug ever to be fixed in Csound? 🤔

Actually not so. That bug was introduced sometime in Csound 5, when we increased the precision of the fixed point maths (in some versions, not all). It went undetected for perhaps 15 years, and I only discovered because I used an extremely long period with an oscili and it went a bit over.

Oh, I've been waiting for this. Thank you.

Say... could that bug fix to the oscil family be one of the oldest bugs to be fixed in Csound...(and possibly the oldest in any software)?

Any questions about brew should go to the brew team. We are not involved in maintaining or making any brew releases. I would expect them to pick up our upstream sources and update their scripts, but I don’t know anything more.
