  2. Agenda • Sound capture devices • Typical set-ups and applications • Connectivity • MIDI set-ups • Portable devices • Sound modules • MIDI controllers • Microphones and speakers B.Sc. (Hons) Multimedia Computing Media Technologies

  3. Agenda (Contd.) • Sequencers • Plug-ins • VST • Audio Units (Au) • Rewire • Legacy Software Instruments • Sample-based sequencing • Mini-Studios B.Sc. (Hons) Multimedia Computing Media Technologies

  4. Sound Capture Devices • Sound cards - Creative Labs de-facto standard on PC • Soundblaster: 16, 32, AWE64 (ISA) Live (PCI) • ‘On-board’ sound hardware • External modules - Prodigy • USB powered modules - e.g. M-Audio B.Sc. (Hons) Multimedia Computing Media Technologies

  5. B.Sc. (Hons) Multimedia Computing Media Technologies

  6. Line v Speaker Connections • Speaker output signal has volume and bass/treble modifications - poorer quality for recording • Line connectors provide a flat signal without any added amplification (gain) or eq. i.e ‘flat’ B.Sc. (Hons) Multimedia Computing Media Technologies

  7. Connectivity phono / RCA XLR(Balanced) stereo jack MIDI mono jack B.Sc. (Hons) Multimedia Computing Media Technologies

  8. Connecting for Stereo TRS – Tip, Ring, Sleeve B.Sc. (Hons) Multimedia Computing Media Technologies

  9. Lots of Connector Variations B.Sc. (Hons) Multimedia Computing Media Technologies

  10. External Sound Modules

  11. External Sound Modules • Solution for mobile computers • Superior sound quality • Distribute system resource loading improving performance of overall system • Better connectivity • Modules with USB BUS power provide for field recording

  12. Portable Devices:Keyboards MIDI keyboard controller (61 keys) B.Sc. (Hons) Multimedia Computing Media Technologies

  13. Portable Devices MIDI keyboard controller (25 keys) B.Sc. (Hons) Multimedia Computing Media Technologies

  14. Portable Devices MIDI keyboard controller (88 semi - weighted keys ) B.Sc. (Hons) Multimedia Computing Media Technologies

  15. Integrated Devices Keyboard controller with integrated sound module B.Sc. (Hons) Multimedia Computing Media Technologies

  17. MIDI Setups B.Sc. (Hons) Multimedia Computing Media Technologies

  18. MIDI Setups B.Sc. (Hons) Multimedia Computing Media Technologies

  19. Speakers • Room acoustics very important • Reference or ‘monitor’ speakers - tell it like it is’ i.e. give no colouration from hardware eq. • Headphones - can be accurate way to monitor sound quality - but speakers considered best sound monitoring device B.Sc. (Hons) Multimedia Computing Media Technologies

  20. B.Sc. (Hons) Multimedia Computing Media Technologies

  21. Microphones • Microphones • Dynamic or Condenser • Omni-directional • Uni-directional B.Sc. (Hons) Multimedia Computing Media Technologies

  22. Microphones B.Sc. (Hons) Multimedia Computing Media Technologies

  23. Dynamic Microphones • Versatile and ideal for general-purpose use. • Use a simple design with few moving parts. • Sturdy and resilient to rough handling. • Better suited to handling high volume levels, such as from certain musical instruments or amplifiers. • No internal amplifier and do not require batteries or external power. B.Sc. (Hons) Multimedia Computing Media Technologies

  24. Microphones: Dynamic B.Sc. (Hons) Multimedia Computing Media Technologies

  25. Condenser Microphones • Condenser microphones require power from a battery or external source. • Audio signal is stronger signal than that from a dynamic. • More sensitive and responsive than dynamics • Good for capturing subtle nuances in a sound. B.Sc. (Hons) Multimedia Computing Media Technologies

  26. Microphones:Condenser B.Sc. (Hons) Multimedia Computing Media Technologies

  27. Microphones: Directional Omni Cardioid Hypercardioid Bi Some microphones provide for adjustable directional qualities - e.g. video cameras B.Sc. (Hons) Multimedia Computing Media Technologies

  28. Software: Sound Sequencers • Synthesized sounds played back via pre- recorded or live MIDI note event data - velocity, pitch, etc. • Sound cards may also have prerecorded digital samples stored on them. • These 'samples' can then be played by sequencing software that will play a number of tracks simultaneously in an ensemble. • Software such as Cakewalk, Steingerg's Cubasis, and Logic Audio Pro.

  30. Virtual Instrument Plug-ins • Plug-in appears in host application • VST (Steinberg Wavelab, Cubase) • Audio Unit (Logic) • Rewire - (Reason) - acts as a slave to the host application. B.Sc. (Hons) Multimedia Computing Media Technologies

  31. What are VST plugins?(VST = Virtual Studio Technology) • VST plugins are generally run within a Digital Audio Workstation, providing the host application with additional functionality. Most VST plugins can be classified as either instruments (VSTi) or effects. VST plugins generally provide a custom GUI (Graphical User Interface), displaying controls similar to the physical switches and knobs on audio hardware. • VST instruments include software simulation (emulations) of well-known hardware synthesizers and samplers, emulating the look of the original equipment and its sonic characteristics. This enables VSTi users to use virtual versions of devices that may be otherwise difficult to obtain. • VST instruments require notes to be sent via MIDI in order to output audio, while effect plugins process audio data. MIDI messages can often also be used to control parameters of both instrument and effect plugins. Most host applications allow the audio output from one VST to be routed to the audio input of another VST (known as chaining). For example, output of a VST synthesizer can be sent to a VST reverb effect for further processing. • With appropriate hardware and drivers, such as a sound card that supports ASIO, VST plugins can be used in real-time. ASIO bypasses Windows' slower audio engine, offering much lower latency. Courtesy: Wikipedia

  40. What is COSM? (Courtesy: Edirol Inc.) • Once a musical instrument generates sound vibrations, it reaches the human ear through various mediating objects, each of which significantly affects the sound. • The material and configuration of the instrument, the electric /electronic /magnetic amplifying system, the air and reverberation of the room all affect the final sound. • Sound modeling, the latest DSP technology, “virtually” reconstructs these objects. Composite Object Sound Modeling (COSM), developed by Roland, uses the advantages of multiple modeling methods and succeeds in accurately emulating existing sounds, as well as producing sounds that have never before been created. • COSM (Composite Object Sound Modeling) isolates and emulates all the various components in the signal chain, from the input of the amp to the final vibration of the speaker cone. COSM then recombines these components to "model" the original amp's setup from tone stacks to speaker cabinets. Further, when these Virtual components are combined, they behave and interact in the same way as the components in the original amp.
