Question: What digital audio software came bundled with Linux's Puredyne?

Context paragraphs:
Audio control surface: In the domain of digital audio, a control surface is a human interface device (HID) which allows the user to control a digital audio workstation or other digital audio application.  Generally, a control surface will contain one or more controls that can be assigned to parameters in the software, allowing tactile control of the software.  As digital audio software is complex and can play any number of functions in the audio chain, control surfaces can be used to control many aspects of music production, including virtual instruments, samplers, signal processors, mixers, console automation, DJ software, and sequencer applications.

Puredyne: puredyne was a live Linux distribution based on Ubuntu and Debian Live and dedicated to live audio-and-visual processing and streaming.  Its focus was on the Pure Data audio synthesis system as well as SuperCollider, Csound and others, plus live video-processing systems such as Processing and Fluxus.  It also included hardware related software such as arduino and came bundled with home-studio and graphic design software (Ardour, JACK, GIMP, Inkscape, etc.).

Echo Digital Audio: Echo Digital Audio designs and manufactures various digital audio recording interfaces, MIDI interfaces, audio test equipment, custom professional audio products, and audio software.  The company is located in Santa Barbara, CA

Ardour (software): Ardour is a hard disk recorder and digital audio workstation application.  It runs on Linux, macOS, FreeBSD and Microsoft Windows.  Its primary author is Paul Davis, who is also responsible for the JACK Audio Connection Kit.  Ardour is intended to be digital audio workstation software suitable for professional use.

Steinberg Nuendo: Nuendo is an audio software product developed by Steinberg for music recording, arranging, editing and post-production as part of a Digital Audio Workstation.  The package is aimed at audio and video post-production market segments, but it also contains optional modules that can be used for multiple multimedia creation and audio sequencing.

MP3: MPEG-1 or MPEG-2 Audio Layer III, more commonly referred to as MP3 (or mp3), is an audio coding format for digital audio.  It uses a form of lossy data compression to encode data using inexact approximations and partial data discarding to reduce file sizes, typically by a factor of 10, in comparison with a CD while retaining a sound quality comparable to uncompressed audio.  Compared to CD quality digital audio, MP3 compression commonly achieves 75 to 95% reduction in size.  MP3 files are thus 1/4 to 1/20 the size of the original digital audio stream.  This is important for both transmission and storage concerns.  The basis for such comparison is the CD digital audio format which requires 1411.2 kbit/s.  A commonly used MP3 encoding setting is CBR 128 kbit/s resulting in file of 1/11 (=9%) of the size of the original CD-quality file, that is with 91% compression.

Magix Sequoia: MAGIX Sequoia is a digital audio workstation.  It is the most powerful of the MAGIX audio software family, essentially offering a superset of MAGIX Samplitude's functionality.  Sequoia is purely software-based, making it independent of proprietary audio hardware.

LADSPA: LADSPA is an acronym for Linux Audio Developer's Simple Plugin API.  It is an application programming interface (API) standard for handling audio filters and audio signal processing effects, licensed under the GNU Lesser General Public License (LGPL).  It was originally designed for Linux through consensus on the Linux Audio Developers Mailing List, but works on a variety of other platforms.  It is used in many free audio software projects and there is a wide range of LADSPA plug-ins available.

Qtractor: Qtractor is a hard disk recorder and digital audio workstation application for Linux.  Qtractor is written in C++ and is based on the Qt framework.  Its author is Rui Nuno Capela, who is also responsible for the Qjackctl, Qsynth and Qsampler line of Linux audio software.  Qtractor's intention is to provide digital audio workstation software simple enough for the average home user, and yet powerful enough for the professional user.

IZotope: iZotope, Inc. is an audio technology company based in Cambridge, Massachusetts, United States.  iZotope develops professional audio software for audio recording, mixing, broadcast, sound design, and mastering which can be used in wide range of Digital Audio Workstation programs.  In addition, iZotope creates and licenses audio DSP technology including noise reduction, sample rate conversion, dithering, time stretching, and audio enhancement to hardware and software companies in the consumer and pro audio industries.
