GRM studio est une application de création musicale . Elle permet de puissantes transformations sonores par la manipulation directe de représentations audionumériques et l’expérimentation de processus de lectures multiples sur des documents sonores. Cette nouvelle lutherie est mise à disposition grâce au soutien du programme Investissements d’Avenir (PIA-SINÉ). Elle complète la collection de ressources de l’INA-GRM disponible sur Éduthèque « Écouter, voir, comprendre les musiques électroacoustiques et les technologies de création sonore » . Pionnier des musiques concrètes, électroacoustiques, acousmatiques, le Groupe de Recherches Musicales (GRM) développe depuis 1958, des dispositifs créatifs de traitement du son à l’usage des musiciens, des compositeurs, des designers sonores Fonctionnalités : - Simulation temps réel des principales transformations du son . Transpositions, time streching, délais, boucles mobiles, synthèse granulaire,etc. - Toutes ces opérations sont faites uniquement en combinant des opérations de lecture d'un fichier sonore. Lecture simple contrôlée en sens et vitesse, déplacement de boucles mobiles comportant plusieurs curseurs de lecture. - Exploration directe de la forme d'onde à différentes échelles - Édition et Montage virtuel

About

BLEASS Spectral Resonator

Transform audio by manipulating its frequency content to create unique spectral textures and resonances. Generate complex harmonic sounds from internal tone generators or MIDI input, with deep control over pitch, timbre, and spectral filtering.

Highlights
  • Spectral domain audio conversion
  • Frequency shifting, blurring, and filtering
  • Internal tone generator and MIDI input
  • Up to eight voices of polyphony
  • Detailed control over resonance parameters
  • Interactive 3D spectrogram visualization
  • Freeze and Kill controls

By converting audio into the spectral domain, BLEASS Spectral Resonator can shift, blur, filter, and restructure the frequency content of any sound before generating resonances. When blended with the source signal, this adds a controllable layer of pitch and timbre. Used fully wet, it produces rich and complex spectral textures. Resonances can be generated from an internal four-voice tone generator or directly from incoming MIDI notes. With up to eight voices of polyphony, glide, pitch bend, and up to 256 harmonics per voice, BLEASS Spectral Resonator can be played from MIDI to create tuned harmonic resonances and evolving spectral textures. Intuitive controls provide detailed manipulation of the resonator behaviour, including unison, detuning, harmonic stretching, density, damping, decay, and harmonic filtering. Harmonics can be restricted to even or odd series, while spectral shifting and blurring further reshape the resulting resonances. A spectral-domain filter lets you select the frequency range used to excite the resonators. The interactive 3D spectrogram visualises resonator activity over time while also providing direct control over the spectral filter. BLEASS Spectral Resonator also includes Freeze and Kill controls for holding or clearing active resonances. Designed to combine deep spectral processing with an accessible interface, it opens new possibilities for harmonic, rhythmic, and dynamic sound design, including inharmonic or atonal material such as drums. BLEASS Spectral Resonator is also available for Desktop. Find more information here: http://www.bleass.com/spectral-resonator

Verdict

The call

The clearest difference is price: GRM studio at Free against BLEASS Spectral Resonator's $19.99. GRM studio also leads on iOS requirement (9.3 vs 12.0). BLEASS Spectral Resonator's advantage is rating (5.0 vs 4.0) and ratings volume (4 vs 1). On ads, in-app purchases and device support there is nothing between them.
