The arpeggio heard throughout "Giorgio by Moroder" was captured in these initial sessions, "with layers of that arpeggio played via MIDI through different synths to create that great sound." Franco described the tests as "very fun and loose sessions", and was pleasantly surprised that some of the parts ended up in the final product.
Harmonic mixing or key mixing (also referred to as mixing in key) is a DJ's continuous mix between two pre-recorded tracks that are most often either in the same key, or their keys are relative or in a subdominant or dominant relationship with one another. The primary goal of harmonic mixing is to create a smooth transition between songs.
High-end commercial audio processing packages either combine the two techniques (for example by separating the signal into sinusoid and transient waveforms), or use other techniques based on the wavelet transform, or artificial neural network processing [citation needed], producing the highest-quality time stretching.
ABC notation is a shorthand form of musical notation for computers. In basic form it uses the letter notation with a – g, A – G, and z, to represent the corresponding notes and rests, along with other elements used to place added value on these – sharp, flat, raised or lowered octave, the note length, key, and ornamentation.
The WAV file is an instance of a Resource Interchange File Format (RIFF) defined by IBM and Microsoft. [3] The RIFF format acts as a wrapper for various audio coding formats. Though a WAV file can contain compressed audio, the most common WAV audio format is uncompressed audio in the linear pulse-code modulation (LPCM) format.
The latter can identify short snippets of audio (a few seconds taken from a recording), even if it is transmitted over a phone connection. Shazam uses Audio Fingerprinting for that, a technique that makes it possible to identify recordings. Musipedia, on the other hand, can identify pieces of music that contain a given melody.
DJs often beatmatch the underlying tempos of recordings, rather than their strict bpm value suggested by the kick drum, particularly when dealing with high tempo tracks. A 240 bpm track, for example, matches the beat of a 120 bpm track without slowing down or speeding up, because both have an underlying tempo of 120 quarter notes per minute.
The program also is capable of opening other sample formats developed by Pixel (.ptnoise and .ptvoice) in addition to some more popular audio formats, such as .wav and .ogg. [1] The primary interface of the program is a piano roll display. It is used to place notes and specify duration, volume, panning, and pitch, among other things.
