AUDIO PRODUCTION TECHNIQUES (TPM) Lab #5 Lab objectives: • Direct sampling (Reason) • Digital audio editing (Reason) • Vocoder BV512 (Reason) • VariAudio (Cubase) TECHNIQUES DE PRODUCTION AUDIO: LABORATOIRE 5 Direct sampling (Reason) Since the fifth version of Reason, it is now possible to sample within Reason. In NN-‐XT, NN19, Redrum and Kong you will find a little waveform button allowing you to sample. The connections in the back of the rack determine the source of input (sound card). Make sure your connections in the preferences are activated. • Reason / Preferences / Audio / Active Input Channels To record a sound source ( i.e : microphone, synthétiseur, modules in Reason), You have to choose your sampling. [Sampling Input] is a virtual connection in Reason that must be connected to an input in Reason. 2 TECHNIQUES DE PRODUCTION AUDIO: LABORATOIRE 5 Editing in Reason It is possible to edit within Reason. All you have to do is to right-‐click on sample -‐> [Edit Sample]. the editing window, will give you three functions. La fenêtre d’édition, une fois affiché permet plusieurs opérations d’édition simples. Try those functions out : • Crop, Normalize, Reverse • Loop / Crossfade Loop • Root Key, etc… 3 TECHNIQUES DE PRODUCTION AUDIO: LABORATOIRE 5 Vocoder BV512 (Reason) A vocoder takes two different inputs; Carrier and Modulator. A vocoder is an effect and not a sound generator so it does not receive MIDI, it receives to audio signals coming from a synth (a rich pads) and a vocal line. Carrier = Synth | Modulator = Vocals. A vocoder uses a series of filters, you can choose how many filter you want in your vocoder (4 bands to 512). More filters = More intelligible vocals. • Patch the vocal line in the [Modulator Input] of the vocoder BV512. • Connect a synth (Thor) in the [Carrier Input] of the vocoder BV512. • Connect the [Output Left/Right] to the mixer. • Make sure that both Carrier and Modulator are modulating on the Vocoder. • Move from 4 bands to 512 bands (FFT) and see how it changes the sound déterminer la précision avec laquelle agira le filtre. VariAudio in Cubase Like Melodyne ou Auto-‐tune, it is possible to correct pitch in Cubase to each note. • From the File menu, choose Import Audio File. • Select the file « Somewhere ». • Once the file is in the project, double click on the Audio region. • The sample editor opens up. • Click on [VariAudio] and activate [Pitch & Warp]. • Identify the false notes and select them (One at a time). • You can now quantize (quantize) and correct the intonation (straighten) of each note. 4
