My pleasure.

Thanks. I'm working on other stuff too, libdolbyb to put

Dolby B encoding and, more importantly, decoding as

many people have old archives but don't want to have to

buy a more expensive Dolby B licensed deck and

spend the money on better heads and electronics.


It's working in sox_ng trunk now, giving bit-for-bit exact

same output as the original Pascal.


I was sniffing ReZound and may get around to it.

It's original developer is still with us but is doing

other things. He seems more interesting in me

implementing or finishing things he was working on

or had in his TODO list but he is responsive

to technical questions so I consider myself to be

blessed in this respect. It's a fab graphical audio editor

whose only lack is a log frequency axis spectrogram display

as an alternative to the waveform. Give me time :)


My latest is maintaining Professor David Turner's interpreter for the

seminal pure lazy functional programming language Miranda

miranda.org.uk


I was Prof. Turner's pupil, then colleague, then friend and

translated the interpreter of his previous lazy flanguage,

KRC, the modestly-named Kent Recursive Calculator, from

BCPL-for-EMAS to C-for-Unix. in the 2000s he even regaled

me damson, the Sparc SunStation on which he had developed

Miranda in the 90's. I remember him bounding up the stairs

to deposit damson in her new home and then being so terrified

of the steep and narrow staircase to descend that I almost had to

carry him down in my arms, bottle-bottom shortsighted that he was.

codeberg.org/DATurner/miranda

It now works on all off the GCC Compile Farm except for, paradoxically,

all Sun Sparc/Solaris machines on which it dumps core as soon as you

ask for 1 + 2.

OK, I'll come clean. I broke ID3-through-LAME writing in 14.5

by including UTF16-writing code that didn't check the return values

from id3_set_fieldvalue() or somesuch and, in fact, it was failing.

I've reverted it and am working on a patch release for 14.5.1

but had to stop today when I found myself screaming at the screen.

The pushers, putas and punkabestia under my window must have

wondered who was doing what to me, but it was just me.


It's OK in trunk, so grab that.

Absolutely! Not only are all CVEs fixed and a slew of grave,

noisy and talkative bugs,but it's now sprouting more stuff.

The new ones are:

* softvol, a volume control that can slowly

increase the volume and, when it would have clipped,

adjust the software volume control so it exactly peaks.

The crunched I expected are totally inaudible, presumably

because they coincide with the peaks of the sound wave

and have latency 0

* a new combining method for sox synth that uses

the synthesized wave to modulate a delay of any length.

Well, up to a year, 15GB.

* dolbyb for Dolby B noise reduction application and removal.

It emulstes in software a real Dolby B unit's electronics,

complete with the calibration procedure in which you have to

earth certain points and adjust some pots until the voltage is

right at some other point on the circuit. I'ts bang on, hats off,

based on dolbybcsoftwaredecode by translating its Free Pascal

into a C library. It doesn't work on bigendian systems yet but

I think it's just a question of how it assembled and disassembles

the samples when they arrive as bytes from a file.

For your need case, I'd provide both a sox interface and

an id3 interface that does the same thing. That way as

working ID3 handling in SoX and id3 comes and goes

your customers will have a working system.

You know where the cookie jar is. Offer me a beer :D
