Zoog ~ Zero Opus Output Gain

Posted by tom2tec on

Zoog is a Rust library that consists of functionality that can be used to determine the loudness of an Ogg Opus file and also to rewrite that file with new internal gain information as well as loudness-related comment tags. It also has functionality for purely manipulating comment tags of both Ogg Opus and Ogg Vorbis files.

Zoog currently contains two tools, opusgain and zoogcomment. opusgain can be used to:

  • set the output gain value located in the Opus binary header inside Opus files so that the file plays at the loudness of the original encoded audio, or of that consistent with the ReplayGain or EBU R 128 standards.
  • write the Opus comment tags used by some music players to decide what volume to play an Opus-encoded audio file at.

It is intended to solve the “Opus plays too quietly” problem.

Incudine ~ Lisp Music & DSP Programming

Posted by tom2tec on

Incudine is used to design software synthesizers or sound plugins from scratch, exploiting the expressive power of Common Lisp, without the constraints of using pre-built unit generators. It is also a compositional tool that produces high quality sounds, controllable at the sample level, while defining and redefining the digital signal processors and the musical structures on-the-fly.

AmiModRadio ~ Aminet Access & Amiga MOD Player

Posted by tom2tec on

A program to automatically download, extract, and play modules from Aminet.

Did you know that, as of today (2015/06/02), there are more than 20,000 packages in the mods directory on Aminet? Yes! That’s more than 20,000 modules to play and enjoy! So, why not have a program that could automatically download one module at-a-time, extract it, and play it? This is the purpose of AmiModRadio.

Essentially, after starting MultiPlayer or HippoPlayer (only at this time), AmiModRadio connects to the player via ARexx and Aminet via FTP, then it downloads randomly a LHA file in the mods directories, extracts its content, and asks the player to play it. 🙂

Features:

  • Connects by FTP to Aminet
  • Uses XAD library to unarchive files containing modules
  • Uses ARexx to request players to play modules
  • Supports MultiPlayer and HippoPlayer

Two flac2mp3 Scripts

Posted by tom2tec on 

flac2mp3 is a perl script that will search for flac files within
a directory hierarchy and convert them all to mp3 format, creating a
matching directory structure in the process.
robinbowes.github.io/flac2mp3
github.com/robinbowes/flac2mp3

This is a python script for transcoding flac files into mp3 files keeping covers, tags, and directory structure. It is multithreaded and creates as much thread as the number of cores on the host. The flac tags will be added to the mp3 files ut8 encoded, and if a cover.jpg file is found in the flac files directory it will be added to the mp3.

The mp3 generated will be itunes compliant (accents, covers) and encoded with lame command :

lame --silent -V2 --vbr-new -q0 --lowpass 19.7 --resample 44100
