for Mobile Devices and Media Players



Today’s mobile phones and UMPCs are highly integrated multi-media communications and entertainment devices with demanding audio needs requiring high performance algorithms and low resource requirements.

With mQSynth™, QSound Labs delivers a high-efficiency real-time MIDI synthesizer for polyphonic ringtones, game music and interactive sound events.

mQSynth offers the optimal audio solution for mobile devices, rendering polyphonic sequenced content including SMF, SP-MIDI, SMAF, MXMF and JSR135, with architectural efficiencies and performance levels that greatly surpass industry benchmarks.



Feature Set Description


mQSynth Software MIDI Synthesizer:
mQSynth plays polyphonic ringtone files, game music as well as interactive real-time sound events using digital wavetable instruments. mQSynth can produce as many simultaneous notes (polyphony) as platform resources allow, and is typically configured for 32, 64 or 128-note capability.

To meet the needs of a broad range of hardware, our standard wavetables start as small as 50KB in size, and range up to over 1MB. Wavetable customization can be provided if special emphasis is desired for certain types of instruments. mQSynth is compatible with the industry-standard DLS (.dls) wavetable format.

mQSynth also supports formats such as Mobile XMF (.mxmf) that include, in addition to the event list comprising the musical score, custom instrument definitions. Real-time interactivity is supported through the Java JSR-135 interactive synthesizer interface and the Java JSR-234 compatible implementation of QSound’s microQ library.

mQSynth’s innovative QSound Realtime Ringtone Remixer (QR3™) automatically re-authors non-optimized content on the fly to produce consistent, high-energy output, free of distortion.



QR3™ Realtime Ringtone Remixer:
Performance-based ringtone files (i.e. in formats such as MIDI) are mainly composed of instructions to the synthesizer (polyringer), rather than digitized audio. Unfortunately, they are not always well-authored for mobile devices. Wide variability in effective signal levels is the result.

QR3 analyses and automatically modifies the performance data before it is rendered into audio by the synthesizer engine, significantly reducing variability. This is especially important for files authored at very high levels, that might otherwise saturate the output.

A second component of QR3 is dynamic range compression applied to the audio output of the synthesizer. This stage reduces variability and increases average signal level.

The net result of QR3 real-time optimization is clean, consistent, high-energy output. QR3 helps every ringtone – regardless of style, instrumentation or level – to punch through background noise.



Technical Specifications and Implementation Data


Audio solutions by QSound Labs have been rigorously optimized with the participation of major industry partners focusing on three critical requirements:


• Quality

• Processing performance

• Memory footprint


You can expect at least 25 to 50 percent savings on MIPS and memory footprint when compared to competing solutions. For detailed technical information and implementation data please contact a QSound representative or email us at info@qsound.com.
