microQ by QSound Labs, Inc

Audio and Voice Solutions

Product Description

microQ® is a compact, modular and highly efficient software digital audio engine enabling polyphonic ringtones, 3D game sound, and enhanced music playback with multiple effects for mobile devices.

microQ represents the culmination of over 20 years of DSP audio software development and product deployment by QSound Labs, a world leader in sonic innovation.

With an incomparable feature set unmatched by any single vendor, microQ’s modular audio suite consists of three major components:

mQSynth™ Polyphonic Wavetable Synthesizer:
Plays polyphonic ringtone files, game music and interactive real-time sound events using digital wavetable instruments. Re-authors non-optimized content on the fly to produce consistent, distortion-free output.

mQ3D™ Positional 3D Audio Engine:
Places multiple sounds independently in 3D space for interactive gaming. Applicable to arbitrary streams or mQSynth synthesizer channels using native or custom instruments and sound effects. Optional: QEM™ environmental modeling (reverberation).

mQFX™ Digital Effects Engine:
Enhances and customizes the music listening experience. Effects include:

QSound Spatial Enhancements:
•QXpander™ 3D stereo sound stage expansion for a natural sounding, less fatiguing listening experience over speakers or headphones.
•QVerb™ digital reverberation effect.

QEQ Spectral Enhancements:
•QSizzle™ dynamic high-frequency enhancement.
•QRumble™ dynamic low-frequency enhancement.
•QEQ™ static multi-band equalization.

QVolume:
•QDRC™ dynamic range controller providing signal level compression or expansion with optional limiting.
•QLimiter™ anti-saturation dynamic range control.

The flexibility of microQ extends into each major component. Consider mQSynth for example: Numerous options include three standard feature packages, support for various API’s/formats, chorus/reverberation effects, all configurable at compile time. Put this together with native DLS sample sets in six standard footprints ranging from 50KB to 1MB, and it’s very likely that we can address your needs with an off-the-shelf solution. If not, further customization of both synth and DLS is available.

Support for Standard Formats & API’s:

microQ renders polyphonic sequenced content (MIDI, SP-MIDI, XMF, mXMF, iMelody, MFi v4.0, SMAF-MA2/MA3/MA5/MA7 with LED, Vibration and .SPF Phrases) with its native wavetable synthesizer sample set or using custom downloadable instruments (DLS, DLS 2.0, Mobile DLS).

microQ plays multiple digital audio formats, both linear and compressed formats (WAV, PCM, ADPCM).
