minBlepy

MinBLEPs library including fast naive waveform conversion.

Install

These are generic installation instructions.

To use, disposably

Install the current release from PyPI to a virtual environment:

python3 -m venv venvname
venvname/bin/pip install -U pip
venvname/bin/pip install minBlepy
. venvname/bin/activate

To use, permanently

pip3 install --break-system-packages --user minBlepy

See ~/.local/bin for executables.

To develop

First install venvpool to get the motivate command:

pip3 install --break-system-packages --user venvpool

Get codebase and install executables:

git clone git@github.com:combatopera/minBlepy.git
motivate minBlepy

Requirements will be satisfied just in time, using sibling projects with matching .egg-info if any.

API

minBlepy

floatdtype

Common data type of naive values and digital audio sample points, effectively about 24 bits.

MinBleps Objects

class MinBleps()

paste

def paste(naivex, diffbuf, outbuf)

Add minBLEPs to outbuf for the differentiated naive signal block in diffbuf. The first element of diffbuf should be the first naive value in the current block minus the last naive value of the previous block. The naivex is the index of the first naive value, modulo naiverate. The outbuf must have enough space for overflow of the last possible minBLEP, and should be initialised to the overflow section of the previous outbuf and otherwise zero.
