Creating Audio with a DAW & Health and Safety
Putting It All Together
This lesson brings together everything from the previous two lessons into a practical workflow. You will learn how to set up a project, capture audio and MIDI, edit and refine your work, and export a finished stereo mix. The second half covers the health and safety considerations that apply in any studio environment.
Applied DAW Workflow
Step 1: Project Configuration
Start by creating a new project. Set the bit depth (24-bit for professional quality), sample rate (44.1 kHz or 48 kHz depending on the destination), and configure the audio output to route sound to your monitors or headphones via the audio interface. Set the tempo (BPM) and time signature to match the piece you are creating. Organise your project with clearly named folders, and save the project immediately. Use keyboard shortcuts (copy, paste, cut, save, undo) throughout to speed up your workflow.
Step 2: Capturing Audio & MIDI
There are several ways to get sound into your project:
- Audio tracks — create audio tracks and record live instruments or vocals through the audio interface. Select the correct input channel, set the gain level to avoid clipping, and arm the track for recording.
- Importing audio — drag existing audio files (WAV, AIF, MP3) directly into the timeline.
- Recording via interface — select the input on your audio interface, adjust the gain so the signal is strong but not distorting, and press record.
- Importing MIDI — load pre-made MIDI files into MIDI or software instrument tracks.
- MIDI controller input — play a MIDI keyboard or percussion controller to record performance data in real time.
- MIDI programming — use the mouse, trackpad or DAW edit pages (piano roll) to draw MIDI notes directly onto the grid.
Six methods of capturing audio and MIDI: recording audio tracks, importing audio files, recording via the interface with correct gain, importing MIDI files, MIDI controller input (real-time performance) and MIDI programming (drawing notes on the grid).
Step 3: Editing & Refining
Once captured, use DAW tools to shape your material:
- Software instruments — assign virtual instruments to software instrument tracks and adjust their settings (synth presets, sampler presets, envelope, filter, waveform).
- Loops — browse and add audio or MIDI loops to fill out your arrangement.
- Editing tools — trim, copy, paste, quantise, adjust velocity, time stretch and pitch manipulate as needed.
- Processing plug-ins — apply EQ, compression, reverb, delay and other effects to shape the tone, dynamics and space of each track.
When the mix is complete, export the project as a stereo mixdown. Choose the appropriate bit depth, sample rate and file format. WAV or AIF for high-quality masters; MP3 for sharing online or streaming. You can also export individual parts (stems) for further processing or remixing.
Health & Safety in the Studio
Studios contain electrical equipment, cables and screens that present real risks. The spec requires you to know about hazards, risks, risk assessment and control measures.
Hazards & Risks
A hazard is anything with the potential to cause harm. A risk is the likelihood that the hazard will cause harm and how severe that harm could be.
The four main studio hazards and their associated risks are:
- Noise — prolonged exposure to loud sound through monitors or headphones can cause hearing loss, which is often permanent and irreversible.
- Displays and workstations — staring at computer screens for extended periods causes eye strain, headaches and fatigue. Poor posture at a badly set up desk or chair causes back pain.
- Slip, trip and fall hazards — cables running across the floor, equipment cases and cluttered spaces can cause falls, resulting in sprains, breaks or bruising.
- Electrical hazards — faulty wiring, overloaded sockets and damaged cables can cause electrocution, burns or fire.
Four studio hazards and their risks: noise (hearing loss), displays and workstations (eye strain, back pain), slip/trip/fall (sprains and breaks), electrical (electrocution). You must be able to identify hazards AND explain the associated risks.
Risk Assessment & Control Measures
A risk assessment is a formal process of identifying hazards, evaluating how likely they are to cause harm and deciding what control measures to put in place.
Common control measures in a studio include:
- Noise — limit listening levels, take regular breaks, use noise-limiting headphones.
- Displays and workstations — position screens at eye level, set the chair so your back is supported, adjust brightness, take regular screen breaks (20-20-20 rule: every 20 minutes, look at something 20 feet away for 20 seconds).
- Slip/trip/fall — use cable management (cable ties, trunking, gaffer tape), keep walkways clear, store equipment properly.
- Electrical — PAT test equipment regularly, avoid overloading sockets, replace damaged cables, use RCDs (residual current devices).
Reporting: Any hazards, incidents or near-misses must be reported to a supervisor or health and safety officer. Accurate reporting helps prevent future incidents.
