Samplers, Sound Modules and Synthesizers tend to be confused with one another, especially as both software and hardware models of these respective devices do now contain some over-lapping capabilities. Essentially, the Sampler tends to come without sound synthesis generation capabilties of oscillation for wave creation or any of the synthesis modelling types. Rather, the pre-recorded, [...]
MIDI instructions and digital audio rely on sophisticated Synthesizers to reproduce sounds of pre-recorded actual instruments and unique synthesized sounds. An important evaluation of a synthesizer, whether as part of a keyboard instrument or attached to the soundcard in the computer is Multi-Timbral and Polyphony. These capabilities are important as a Sequencer can create many [...]
A Sequencer is either a software application installed on a computer, or an application residing in a stand-alone hardware sequencer, that will process and organize the MIDI instructions into various instruments and notes and replay the performance. The Sequencer also allows one to edit the performance after the data has been stored on the hard [...]
Rather than work with large digital audio files, one can also work with MIDI data that sends instructions to hardware devices and software applications to play sounds (in real time or saved to a file) based on performance information.
MIDI is not a digital audio file that one can play and hear sound. Rather, MIDI are [...]
Computers have their own specific hardware configurations and Operating Systems.
The processing of digital data based on a mathematical equations can be broken up into a group of simple equations. These simple equations are based on the logic statements of “OR” and “AND”. This two choice mathematical option is processed electronically by a circuit being opened [...]
Introduction
Sound production requires a combination of hardware and software. All of these components range from basic inexpensive introductory versions to very expensive and complicated professional versions. The most recent off-the-shelf Apple Computers models and MS Windows / Intel models (with a minimum of a SoundBlaster Live sound card) can function as the platform for a [...]
Samplers, Sequencers, Sound Modules and Synthesizers (both hardware and software) sometimes require a proprietary digital audio file format. Many hardware and software audio production devices and applications will work with PCM .wav and .aiff digital file formats.
One can purchase CD-ROMs (in .wav, .aiff or as CD-Audio that one must extract and convert to either [...]
Digital audio can be streamed over the internet or downloaded and played through a web browser in various formats.
Digital audio can also be delivered over the World Wide Web in streaming audio (compressed for delivery, downloaded but not saved to hard disk) or downloaded (compressed for delivery and then saved to hard disk) over the [...]
The idea behind compression is to have the highest audio quality possible at the lowest bit-rate in order to save either storage space or bandwidth transmission requirements. Some Codec applications rely upon algorithmic equation (procedure) to read the signal mathematically and eliminate some information based on psychoacoustic perceptual audio coding. The data that is retained [...]
CD Audio is specified as linear PCM, 44.1KHz sampling rate and 16-bit, stereo resolution. The data is allocated within frames, which allow 24 bytes of data per frame. The frames are interleaved with other non-sequential frames of data. Included in with the digital audio data is additional data on error correction, synchronization, and display.
