ARTIFACTS | Audio Artifacts | Audio tracks include audible artifacts such as "ticks", "pops", "crackle", "hiss", etc. | 1.0 |
BIT-DEPTH | Bit depth incorrect | Bit depth is incorrect. For example, 16-bit audio provided when 24-bit is expected. | 1.1 |
BITRATE | Audio Bitrate Is Below Spec | Audio bitrate is lower than specification in platform requirements. | 1.0 |
BUMP | Bump | Extraneous sound that does not sound natural in context. Usually lower frequency sound. Short in duration. | 1.1 |
CHANNEL-ASSIGNEMENTS | Incorrect Audio Channel Assignments | Audio Channels are not assigned correctly in the header/metadata of the file (e.g., 5.1 + Stereo .mov files with all channels assigned as 'mono'). | 1.0 |
CLIPPING | Clipping | Increased audio levels exceeding the technical spec for the format, causing flat-lining of the audio peaks which may result in distortion or clicking. Could be clipped at 0db or also clipped lower due to a problem with a source file. When DISTORTION is known to be caused by clipping, it should be reported as CLIPPING. | 1.1 |
CONFIGURATION | Incorrect Audio Configuration | Audio channels are not in correct order or missing per specification in platform requirements. This term also accounts for extraneous tracks or channels which are not allowed. | 1.0 |
CONTENT-POLICY | Content Does Not Adhere to Agreed Policy | Content does not adhere to platform's policy due to issues such as offensive language or sounds. Can address content ratings, censorship, or other policies. | 1.1 |
CORRUPT | Corrupt Audio | Audio file or track will not open, playback or transcode. | 1.0 |
CRACKLE | Crackle | Crackle is similar to Pop/Click/Tick, but of longer duration (multiples). See POP-CLICK-TICK, SNAT | 1.1 |
DISTORTION | Audio Distortion | Audio sounds overmodulated. | 1.0 |
DOUBLED-AUDIO | Doubled Audio | A sound element is doubled on top of itself, playing twice, similar to an echo or causing phasing issues. | 1.1 |
DROPOUTS | Audio Dropouts | Audio contains one or more unintentional sections of silence. | 1.0 |
DYNAMIC-RANGE | Dynamic range is not what was expected | Audio tracks that are expected to be full range are limited range; or when limited range is expected, full range is provided | 1.1 |
INCORRECT-AUDIO-ELEMENTS | Track contains incorrect elements | Track contains unexpected elements based on the configuration. For example production sounds identified on a dialog stem. | 1.1 |
INCORRECT-CONTENT | Audio Asset Is Incorrect Content | Program Audio does not match title, description, file name, ID or corresponding video file when delivered as a discrete asset. | 1.0 |
INCORRECT-CONTENT-DUB | Incorrect Dub Vocals track | Special case of INCORRECT-CONTENT where Dub is incorrect. | 1.1 |
INCORRECT-DOWNMIX | Incorrect downmix | At some point, channels were downmixed to an incorrect configuration. For example, 2-channel stereo audio was mixed to 2-channel mono audio (both channels identical); sometimes called mono-summed. Another example is incorrect downmix from 5.1 to 2.0. Special case of CONFIGURATION. | 1.1 |
INCORRECT-LANGUAGE | Audio Is in Incorrect Language | Audio language does not match language flag or filename. | 1.0 |
INVALID-CODEC | Invalid CODEC | Audio encoded with codec that is not accepted within the specification. | 1.1 |
LEVEL-SHIFT | Shift in level | The audio has an abrupt shift in volume unmotivated by picture. | 1.1 |
LOUDNESS-ERROR | Loudness violates norms. | Calculated loudness, such as using LUFS/LKFS, is outside specified limits. This is dependent on whatever specification applies. | 1.1 |
LOW-LEVELS | Low Audio Levels | Audio loudness is low relative to specification in platform requirements. | 1.0 |
MISSING-DIALOG | Missing Dialogue | Audio mix is incomplete with no dialogue present. | 1.0 |
MISSING-EFFECTS | Missing Effects | Audio mix is incomplete with no sound effects present. | 1.0 |
MISSING-MUSIC | Missing Music | Audio mix is incomplete with no music present. | 1.0 |
MIX-BALANCE | Mix/Balance | General category that covers issue in the mix, either from the balance or volume on certain channels. For example left channel is louder than the right channel. This can include incorrectly located sounds, either because of mislocated objects or incorrect channel usage. For example, an explosion could come from the wrong place, or an object moving onscreen from left to right might have audio that moves right to left. See SHIFT, INCORRECT-DOWNMIX. | 1.1 |
NO-STREAMS | No Audio | Source file contains no embedded audio tracks. | 1.0 |
OTHER | Other | Any issue not covered by the standard terms and definitions. | 1.0 |
OUT-OF-PHASE | Audio Channels Are Out of Phase | Audio channels within a mix are audibly out of phase with one another. | 1.0 |
PAN-SHIFT | Shift in image (pan) | The audio has an abrupt shift in imaging (pan) unmotivated by picture. | 1.1 |
PEAK-OUT-OF-RANGE | Peak/Out-of-Range | The audio peak level of an event or effect exceeds the format specification. | 1.1 |
POOR-QUALITY-COMMENTARY-DESCRIPTION | Poor Quality Commentary or Description | Audio quality of Commentary or Description is not crisp and clear, but muddied, garbled, or subject to distortion or generation loss which creates a poor listening experience. See POOR-QUALITY-MAIN, POOR-QUALITY-DUB. | 1.1 |
POOR-QUALITY-DUB | Poor Quality Dub | Audio quality of Dub is not crisp and clear, but muddied, garbled, or subject to distortion or generation loss which creates a poor listening experience. See POOR-QUALITY-MAIN, POOR-QUALITY-COMMENTARY-DESCRIPTION. | 1.1 |
POOR-QUALITY-MAIN | Poor quality main mix | Audio quality of main mix audio is not crisp and clear, but muddied, garbled, or subject to distortion or generation loss which creates a poor listening experience. See POOR-QUALITY-COMMENTARY-DESCRIPTION, POOR-QUALITY-DUB. | 1.1 |
POP-CLICK-TICK | Pop/Click/Tick | An out of place pop, click or tick on the soundtrack, could be from bad digital processing, a bad splice, weak signal, microphone noise, or any number of other causes including mouth noise, clicks. Terms are interchangeable. See CRACKLE, SNAT | 1.1 |
SAMPLE-RATE | Sample Rate incorrect | Sample rate is incorrect. For example, 44.1 KHz provided when 48 KHz is expected. | 1.1 |
SCRATCH | Scratch | An unexplained audio anomaly, could be an out of place ripping noise in the audio track, generally refers to a result of an analog recording issue or a transfer from an older legacy optical soundtrack source. | 1.1 |
SILENT | Audio Channel Silent | One or more audio channels in a source are silent (e.g., Silent Left Surround and Right Surround within a 5.1 mix). | 1.0 |
SNAT | Snat | Usually digitally created. Sharp change in waveform. See POP-CLICK-TICK, CRACKLE. | 1.1 |
