Recording & Wave Editing Basics
Recording Basics
Determine the characteristic of the record:
Atmo -> STEREO
Sound object -> MONO
Choice of the microphone
Optimal time and location for recording
Allow enough time!
Take into account cutting when recording
If you think the sound is over, count on 3 again ...
Recorded distance influences character of the recording (and level!), keep recording distance and angle constant over takes -> consistency
Correct recording level: plan enough headroom (in relation to the expected dynamics of the signal)
Wave Editing
Basic
Denoise (Edit > Noise Reduction / Restoration > Noise Reduction (process) or cmd/ctr+shift+p)
Cut at zero-crossing (Edit > Zero Crossings > Adjust Selection Inward (Shift+i) or Adjust Selection Outward (Shift+o))
(Convert to mono (Edit > Convert Sample Type or: shift+T))
Normalize to -2db (Effects > Amplitude and Compression > Normalize (process))
fade-in / fade-out if abrupt start or end of sound
Further options
Edit individual sample points (via HUD)
Leveling
AMP (amplifier) envelopes
Filtering (high-pass, low-pass, bandpass), equalizing
File formats, sample rate / bitrate set
File management: naming, export multiple
File formats / Save
Formats: Uncompressed (PCM, eg in aiff or wav container), lossless (eg in flac, apple & wma lossless) / lossy Compressed (eg as mp3, ogg, wma, mp4)
Sample rates: 8 - 192khz
Tips for naming files
For a soundlibrary, terms make sense that characterize the sound in general, eg. according to material and "morphology" of the sound. So you can find the sounds again. Examples:
“beer_can_metal_impact_sharp_long_resonance”
“fingernails_scratching_wood_dull”
“small_tonal_ding_glass_repeated”
If you have a concrete, known process, e.g. a coffee machine or a kitchen blender, etc. then it is worth saving the whole noise under this name, and adding any qualities (eg coffe_maker_steamy_sharp_hiss ")
If you have a sound that is (kind of) similar to the sound of a motor or something else concrete, so where a "purpose" is audible, then that could also be in the name, but not only.
Sometimes it makes sense to make a note about the recording technique, especially when creating variants, eg:
_closeup
_distant
_stereo
_….
