Csound vs Quanta 2

Csound is a free sound and music computing system for creating music software and making music. Its uses include electroacoustic works, algorithmic jam sessions, app development, and game audio projects. The programming system offers more than 1,500 opcodes and supports traditional and functional syntax. Getting-started material demonstrates MIDI keyboard input, real-time audio input, synthesis, envelopes, and filtering. Csound code can run in a browser through the Csound Web IDE or be explored interactively in the FLOSS Manual without installing Csound. The project links frontends including Cabbage, CsoundQt, and Blue, plus wrappers or interfaces for JavaScript, Python, Unity, Android, and iOS. Downloads or packages are listed for Windows, macOS, Debian, Ubuntu, Fedora, Arch, Android, and Web Assembly. An iOS SDK is also linked, and the latest Csound 7 beta installers for iOS are available through the relevant GitHub Actions page. The download page notes that Apple or Windows may warn that Csound is not trusted because the project cannot pay their licensing costs. Support channels include mailing lists, a forum, Discord, Slack, and Stack Overflow.

Quanta 2 is a granular synthesizer plugin for shaping imported audio samples into playable sounds. Its grain engine can produce up to 100 simultaneous grains per voice and works with AIFF, WAV, Broadcast WAV, FLAC, MP3, and Ogg files in any sample rate, bit depth, or channel configuration. Two virtual analog oscillators and a noise source add other sound sources, with dual filters that can run in series or parallel. Modulation includes four envelope generators of up to 99 steps each, two LFOs, sample and hold, and four assignable macros. Chorus, stereo dual delay, and reverb are built in. Quanta 2 supports MPE controllers, MTS-ESP microtuning, and TUN-format tuning tables. Desktop plugin formats are VST3, AU, AAX, and CLAP; the iPhone and iPad version is AUv3 and is sold separately. A fully functional demo has a 20-minute session timer and disables saving. The listed desktop license is $99 as a one-time purchase, with no subscription or DRM. A 2026 update added real-time recording and additional filter modes.
