What Is Audio Editing
Audio editing involves intentionally modifying recorded audio to improve its quality and clarity, while creating specific effects. It includes trimming, splitting, merging, mixing, fade in/out, adjusting volume, adding effects, removing unwanted sounds, and more. These techniques help creators improve their audio, resulting in professional-level content.
What Are Three Types of Audio Editing Techniques
Audio editing techniques can be mainly divided into three categories: permanently altering audio, preserving the integrity of the original audio, and creating new sounds. The specific methods used to accomplish these tasks can be categorized into three main types: audio cutting, audio fading, and audio mixing.
1. Audio Cutting
Audio cutting is the process of removing a part of an audio file, aiming to shorten or mute it, or delete undesired parts. It usually includes two aspects: audio trimming and splitting.
Trimming audio refers to controlling the two edges of the audio layer in an editing program to shorten the beginning or ending. Splitting audio means separating a complete audio track into two or more clips, which can be deleted, edited, moved, and so on.
Audio cutting stands as the most fundamental audio editing technique, commonly applied in video production, podcasting, and music composition to remove any annoying stops, optimizing rhythm flow and audio quality.
Audio cutting primarily emerged with the rise of audio recording technology in the 20th century. With the advent of tape recording, vinyl disc recording, and digital audio workstations, producers gained the ability to manipulate sound with greater precision, making this practice increasingly commonplace. In the latter half of the 20th century, the emergence of hip-hop and DJ culture further expanded the use of “audio cutting,” making “audio cutting” techniques central to creative remixing and sampling.
2. Audio Fading
Audio fading can be mainly categorized into three aspects, including fades in, fades out, and crossfades, which refer to the process of gradually increasing or decreasing the volume of an audio signal. Fade effects are commonly used in audio production. They can create smooth intros and a gradual fading musical ending to avoid abrupt entries and pauses.
Additionally, this technique enables seamless connections between audio segments—known as crossfades: as the current segment fades out, the subsequent segment fades in, producing a seamless transition effect.
3. Audio Mixing
Audio mixing is the process of integrating numerous audio tracks into a single cohesive track by changing volume levels, frequency characteristics, and spatial positioning.
Compared to audio cutting and audio fading, mixing is a more complex process that involves applying various effects and using tools, such as equalizers and compressors, to create a balanced, refined, and clear-sounding audio output. When mixing audio, it’s usually necessary to adjust the volume of every track, ensuring that every sound reaches the desired loudness to balance levels.
Sound Editing vs Sound Mixing
Sound editing is a post-production project, which includes audio assembling, tweaking, merging, cutting, and re-recording. Most audio editing occurs in the production stage. This includes every phase of the production process, including sound effects, post-production dubbing, and on-set shooting and recording. Editing is necessary for any procedure that produces new audio content.
Compared to sound editing, sound mixing, on the other hand, focuses more on further refining and perfecting the edited audio during the post-production stage. Mixing involves combining these edited clips to create a cohesive, complete audio composed of dialogue, sound effects, music, etc.
| Sound Editing | Sound Mixing | |
| Main Purposes | To merge, trim, create, and polish sounds. | To balance and blend multiple sounds into a harmonious mix. |
| Activities | Create sound effects, edit dialogue, fade audio clips, overlap audio, etc. | Balance volume, panning, equalization, compression, etc. |
| Time | Before sound mixing. | After sound editing. |
