Domestic Elements Hardware Processing and One Shots
One Shot Hits Kicks and Snares
The most basic sounds/samples in a sample library are the individual one shot kicks, snares and percussion sounds that lead on to making up the loops fore the library. The individual hits are the fundamental building blocks of the sample library so it is important to ensure that these sounds are of good quality as well as having some unique characteristics.
The majority of one shot kicks and snares were to be created within Reaper where cutting, editing and pasting audio was quick and simple to execute. The actual individual hits would be taken from the initial sound recordings of all household objects from the initial recording sessions.
For creating the snare sounds, having a wide variety of sounds was important so some creativity would be practiced in creating unique hits. The relevant Foley recordings such as light switch clicks, drawer slams and door slams would all be used and manipulated into usable snare hits.
All of these sounds would be cut and edited from the original recordings, leaving a short audio file that closely resembled the character of a snare hit. Many of these sounds would need to be processed in order to make the sound more interesting, adding more character to the sound.
The familiar processes of EQ, compression, saturation processing, reverb and echo were all applied to the individual sound at this stage with freedom to experiment with sounds until the desired results were achieved.
An example of this would be in attempting to create the sound heard on many Dub Reggae tracks. Reverb and echo would be used extensively on these types of sounds along with some EQ boosts in the 1 KHz to 5 KHz range, providing a snap to the snare sound which enabled the sound to cut through any mix effectively.
The sound of a leather chair being slapped was the main basis for this sound and once processed, was useful for the type of sound I was attempting to achieve. Processing wasn’t the only method used to create unique snare type sounds.
Layering different individual hits together was also an effective method of giving unique character to a snare hit. Blending 2 or 3 sounds together with different frequency ranges and adjusting the levels of each sound appropriately, was an effective method of creating composite sounds from the raw Foley material.
The main advantage of this technique is the unique range of sounds that can be created from layering and adjusting the levels of each sound. This technique can add more depth to the individual snare hit without using extreme sound processing such as EQ and compression although processing techniques were prevalent throughout the process also.
Having some differing approaches to sound production and creation would help provide a wider range of sounds for the library. The layered snare sounds were put into the library under the snare hits folder and would remain untreated, leaving the user the option of further processing to those sounds if desired.
The creation of the individual kick drum files was handled in a similar manner to the snare hits although, effects such as reverb, delay or any form of modulation effects were avoided as these aren’t particularly suitable in the creation of kick drum sounds due to the low frequency content of the raw material.
The most effective method of creating the kick sounds , tended to be the layering technique where the low end thump at around 80Hz could be the basis of the sound and a higher frequency percussive hit would then be layered underneath and EQ’d slightly, in order to give the kick some attack in the mid range.
This process would be repeated in varying degrees to create a kick drum folder, the intention being to allow a user to create their own loops from scratch or to add to the provided loops where the user can enhance the loop with extra kick or snare hits, enhancing some aspects of the rhythm.
Hard Ware Processing
Throughout the project, software plug in processing was prevalent in all stages of processing and was invaluable in all processing tasks, from subtle EQ to extreme reverb and delay settings. These plug ins were effective in all of these areas but my intention with this library, was to create a unique product which contained a variety of sounds with individual character.
Another method of processing, therefore, which would be utilized in sound processing tasks , was to use analogue hardware processing units to create sounds in real time which would be recorded as audio into Pro Tools and edited into looped audio within Pro Tools. The hardware processors used at this stage included the Dbx 266 XL compressor, Line 6 echo pro, Korg Kaoss Pad and various guitar effects pedals, all of which were capable of producing unpredictable, unusual and interesting sounds.
The first stage of the process, involved connecting the hardware processors to the digital audio interfaces using conventional analogue ins and outs, cables and the processors themselves. This meant that some basic signal routing, gain staging and checking of levels between different pieces of equipment would all have to be carefully monitored.
The equipment used would involve two separate audio interfaces, a laptop and desktop computers as well as the processors and cabling that would connect this system together.
To process a sound using hardware, the sound would be loaded into a project within Reaper and constantly looped. The Pod UXT2 digital audio interface which is connected to the laptop is the output source for the loop in Reaper and would be connected to the processor in question and the processor would then be connected to the inputs of the M box2 which would direct the sound into the Pro Tools software.
The important element at this stage, was to check the levels at each stage, from the output channels in Reaper to the outputs from the processor into Pro Tools, with the intention being, to obtain a strong signal into Pro Tools without any peaking. The following, is an example of the process where the processor used is the Korg Kaoss Pad.
Korg Kaoss Pad
The Korg Kaoss pad is an interesting effects processor that relies on hands on manipulation of effects on audio material in real time. The unique aspect of this unit is the central touch sensitive pad which is used to manipulate the effects.
These effects range from filter effects to reverbs and extreme delay settings. The touch sensitive pad allows the effects to be manipulated in a manner which wouldn’t be possible with knobs or faders and offers an intuitive method of sound processing. This is ideal for the creation of interesting sounds which may not have been previously possible.
The following example highlights one particular method where, organs note was manipulated using the Korg Kaoss pad.
The first stage of this process involved setting up the one note organ drone, previously created in the library from the time stretched bowed glass sample. This organ note was looped over 2 bars in Reaper and then connected to Pro Tools via the Kaoss Pad.
The levels at all stages were adjusted so as to maintain the strongest signal to the lowest amount of background noise. The effects on the Kaoss Pad are selected via a rotary knob which runs through the effects banks within the unit.
Once the desired effect is selected, the effect then only becomes activated whilst touching the central pad. Moving the fingers on the pad then manipulates the effect parameters, enabling the user to create effects which can be as subtle or extreme as desired.
For the purposes of creating the Pure Phase sample, the phase modulation effect was selected and was changed over time by running my fingers over the pad in a circular motion as the original organ note played. Once satisfied with this treatment, the performance was recorded into Pro Tools as audio. Once the audio had been recorded into Pro Tools, it was edited slightly with minor cuts at the start and end of the audio region which was then looped in Pro Tools to ensure the audio looped cleanly without any glitches.
Once this was completed, the region was bounced to disk, named and saved as a WAV file within the relevant folder. Essentially, this process was a method of re sampling material already created from the raw material recorded at the start of the project and was a process repeated throughout the project.
This technique of using hardware processing to manipulate existing samples was a creative method of manipulating sound into different forms and showed the creative possibilities in re sampling audio created for the library. These techniques have been a mainstay of sampling culture since the emergence of digital audio technology and this influenced my decision to incorporate some of these re sampling and real time processing techniques into the practical aspects of the project.
All of the samples created from hardware processing would be stored in specifically named separate folders.
The library was intended to be easy to use and clearly laid out. Several categories were created relating to percussive, harmonic and one shot hits as well as the processed and unprocessed sounds.
Much of the research I had undertaken on commercial sample libraries was useful in making decisions on the type on content that would be included in the library. The intention was to provide a wide range of sounds which could be incorporated into most modern electronic genres but particularly genres such as ambient , down tempo beats, dub step and electronica.
The categorization of many of the folders would be designed to cater for these specific genres and this was important to the overall aesthetic of the library and the market it would cater for.
When examining the layout, the priority was to separate the rhythmic loops and beats into separate folders from the harmonic content , notes, drones, special effects and atmospherics folders. The beats and rhythmic loops would be further categorized into separate BPM folders, specifically labeled from BPMs 60 to 140.
This was important in terms of how a user would negotiate the library layout. A producer or musician may have a specific idea of the BPMS of any project that they are working on so labeling the folders in categories of tempo, allows the user quick ,easy access to the material that may be useful foe their work in progress. This ease of use for the library makes it a more attractive product and increases the functionality and user friendly capabilities of the library.
All of the harmonic content including chords and notes were also to be categorized into folders relating to specific chords and notes.
An example of this would be where the G maj 7 chords created would be stored in the G ,A and B chord folder, irrespective of the actual sound characteristics of the chord.
The reasoning behind this method was focused on making the library as user friendly as possible. A user could quickly load a file into a project, mapping the G maj 7 chord to middle C . This gives the user a quick reference point from which to build a track as they can quickly determine the root note of the chord and build other elements in the track around the pre determined G maj 7 chord without wasting too much time on trying various other notes and chords to find which combinations may or may not work musically.
The individual notes used to build the chords were also included separately within the library. Doing this, would allow the user to go deeper by mapping a C note from the library to middle C in a software sampler. The sampler can then be physically played using a Midi keyboard interface, allowing the user to create their own chords from the source note or play sequences in real time via the Midi controller.
These options were provided to appeal to as Many potential users as possible, from skilled keyboard players to artists that may require ready made chords , chord sequences and arrangements on which they could then build on further by manipulating the sounds to create their own arrangements without the need to play an instrument.
Categorizing folders, naming them clearly and arranging them in a logical fashion, were all essential in providing a functional user friendly sample library.
