• POST/audio-description-script$0.02Finds scene cuts with the ffmpeg scdet filter (scene_threshold on a 160 px wide copy), takes speech from caption cues when captions are supplied, otherwise detects it in the audio with Silero VAD v6.2 (or an energy detector). Pauses between speech, shortened by padding_s at both ends, become description slots when at least min_gap_s remain; each slot gets a word budget at words_per_minute (no standard rate exists; 150 wpm is a common narration pace, set your own) and the scenes it touches.

In duck mode every description starts at at_s (or right after the previous one) and the soundtrack is lowered by duck_db while it plays; in extend mode the soundtrack pauses at at_s for the length of the description plus 0.2 s (extended audio…

• POST/background-voice-detect$0.02Decodes up to 2 minutes (mono, 16 kHz). Frame levels (20 ms window, 10 ms hop) give the overall 95th percentile and the noise floor (10th percentile); levels are reported relative to the 95th percentile of foreground frames. YIN (de Cheveigné and Kawahara 2002) marks voiced frames with f0 70–400 Hz.

• POST/burned-subtitle-extract$0.03Crops the subtitle band (band_top to band_bottom of the frame height) and samples it at sample_fps. A text mask keeps bright pixels that have a dark neighbour within 2 px (outline or shadow; the reverse for dark text). A cue is a run of samples with a mask present whose consecutive masks overlap (IoU at least 0.5); runs shorter than min_cue_s are dropped.

The constant offset is the shift within ±max_offset_s that maximises the agreement (Dice coefficient 2·|captions∩speech| / (|captions| + |speech|)); overlap is the share of caption time that has speech.

• POST/codec-history$0.02Reads codec, bitrate and encoder tags with ffprobe and decodes up to 60 s (mono mix, native rate up to 96 kHz). The encoder lowpass is found as a spectral cliff in a Welch long-term spectrum (15 dB criterion, see true-bandwidth). For MP3 the cliff is compared with the LAME 3.100 lowpass table (optimum_bandwidth() in libmp3lame/lame.c): a cliff more than 1.5 kHz below the value expected for the declared bitrate means the content was probably encoded before at the bitrate whose lowpass is…

November 2026, %, € and & spelled out, and main clauses joined by ", und/aber/oder/denn/doch" or ";" split into separate sentences when both parts have at least three words.

• POST/feed-fulltext-search$0.003Indexes up to 300 supplied transcripts (WebVTT, SRT, Podcast Namespace JSON or HTML, plain text) per call and searches them; nothing is stored between calls and no feed is crawled. Passages are cues (word-level JSON merged into sentences); tokens are lower-cased with diacritics folded (ß = ss).
  Example

• POST/feed-loudness-series$0.01Feed mode: takes the newest 1-4 episodes of an RSS feed and fetches only a byte range of each enclosure (by default from the middle of MP3 files, from the start for other containers; large ID3 tags are skipped), so every value is an honest sample measurement, not the loudness of the whole episode. Clip mode: measures 2-6 supplied audio files completely.
  Example

  curl -i -X POST 'https://ton.halowerk.com/v1/feed-loudness-series' \

Per pixel, relative luminance follows the WCAG 2.2 sRGB formula; a transition is an opposing change of at least 0.1 between a peak and a valley where the darker state is below 0.80 (general flash).
  Example

The MPD comes from ffmpeg (SegmentTimeline; bandwidth replaced by the measured peak segment bit rate).
  Example
