built 628 days ago
About SRS Labs, Inc. SRS Labs is a leader in audio signal processing for consumer electronics. Founded in 1993, SRS Labs holds 129 worldwide patents, with another 34 pending, for advanced audio, voice and surround sound technologies that optimize and improve the listening experience through techniques based on research into the human auditory system. Through partnerships with leading global manufacturers and semiconductor and software partners, over one billion products have shipped worldwide utilizing SRS audio technologies, primarily from one of three main technology families, SRS WOW(R), SRS TruSurround(R) and SRS Circle Surround(R). SRS Labs audio and voice processing provides the best possible sound from all content and in every environment including HDTVs, mobile phones, portable media devices, A/V components, PCs and automotive entertainment. And with 38 percent of the 58 million flat panel televisions shipped in 2006 featuring SRS audio processing, SRS Labs is the de-facto standard of HDTV audio processing. Additionally, SRS Labs surround sound solutions provide the professional broadcast and recording industries with high-performance production, back-haul, storage, and transmission capability.

After completing this multi-media course you will be well-equipped to start creating your own audio and signal processing applications within the LabVIEW development environment. The modules in this course make extensive use of "screencasts" -- videos captured directly from the computer screen that show the LabVIEW tool in operation, with audio narration to explain each step. The course includes a "Getting Started" tutorial, editing tips, essential programming structures, subVIs, arrays, audio sources, audio output to the soundcard, reading and writing audio files, and real-time audio output with interactive parameter control. This course is part of the series "Musical Signal Processing with LabVIEW".

The course is based on Rose-Hulman ECE481, a music synthesis and audio signal processing course originally taught in a classroom. Online, the course is a substantial work, with over 50 Modules populated with more than 100 Screencast videos -- narrated videos of computer screen activity. The Screencasts embody the theoretical exposition with handwriting, diagrams, and animations drawn on a tablet device, and ... demonstrate NI LabVIEW programming techniques to implement the concepts.

SRS Volume IQ uses psychoacoustic principals to analyze and address the perceived level (volume) changes in an audio signal. The process is designed to minimize undesirable artifacts while accurately maintaining a reference volume level and producing a high-quality audio experience. Unlike traditional AGC processes, SRS Volume IQ is based on human loudness perception models and multi-band signal analysis. Additionally, SRS Volume IQ is extremely efficient in resource and memory usage compared to other solutions on the market and it supports mono, stereo and multichannel processing. SRS Volume IQ can be applied to any audio-enabled device including televisions, set top boxes, AV Receivers, PCs, mobile phones and portable media devices.
