Louie, The audio dictionary (3rd ed.), (Seattle: University of Washington Press, 2005), 114-115. Listen to analog distortion on SoundCloud. I can turn the volume down on the track so its not so overpowering, but Im hoping theres a way to ameliorate the distorted sound when his. If the original audio signal is clipped because it was too loud, the only way to eliminate the distortion is to re-record the audio at a proper level. It is careful to keep this in mind while cleaning up the recording for production masters or access copies. Ive got a podcast to edit and one particular track is awfully distorted, due to the user having the gain up on their mic, and speaking extremely loudly. Removing distortion is a balance between taking out undesirable frequencies while keeping component frequencies that make up the harmonic of a sound unaffected. Post-production, there are several tools available that are well suited to spectral repair and fixing overloads:Īttempts to remove distortion noise may adversely affect the harmonics of a sound and thus change the quality of the voice or sound that was captured. When the distortion is in the source recording, there is not much that can be done during digitization to correct it. Unfortunately, most unique and archival recordings were done by non-professionals, who made simple mistakes, which are difficult to fix. “Hot levels” means that the input signal level exceeds the recording device’s linear range, and is also known as “overload.” The volume is too high throughout the recording, and thus all distortion artifact noises are also loud. When a signal hits this brick wall, the waveform will distort as peaks are truncated. If the audio source volume is in the top 25 it. To address this, there are a few steps to take: Reduce the volume on the audio source to about 75 of maximum (Phone, PC etc). If the audio feeding into the speakers is loud or low quality, the speakers further amplify it. In this artifact guide, analog distortion is the term used to describe a recording where the levels are too hot in the source recording. One of the main ways to make a master loud is by using brick wall limiting however, this is the primary cause of distortion during mastering. Often, the distortion that can appear in many speakers is a result of the audio source.

1 Analog distortion is an artifact recorded into an analog carrier or introduced in an analog signal chain, while Digital Distortion occurs during digitization and post A/D conversion. This is somewhat of a catchall term for such artifacts as Wow and Flutter that are, by definition, a distortion of the original signal. In audio, distortion is heard as an unwanted signal change.
