👑 qwavsilence — the quelcom manual, bestie edition 💖

okay so welcome to qwavsilence(1), part of the quelcom man pages ✨ this is the one that sniffs out silence in your wav files and can literally shrink it away. sit down, grab a strawberry 🍓, we're doing this.

✨ NAME ✨

qwavsilence — detect and shrink silence sequences in wav files 🎀

---

🌸 SYNOPSIS 🌸

qwavsilence [option]... file...

---

💅 DESCRIPTION 💅

so basically qwavsilence reads a list of wav files and goes looking for silence sequences. that's the whole vibe. it reads them, it finds the quiet bits. no cap. 🦋

---

✨ OPTIONS ✨

• -d <duration>[<format>], --duration=<duration>[<format>] — duration is a positive integer that tells you the minimum duration of a silent sequence in a file for it to actually get reported. the value counts as a sample number unless you slap a format specifier on it — peep the FORMATS section below for the tea. default is one second 👑
• -h, --help — show a lil brief help and dip. bye bestie 🫶
• -S, --shrink — when this is set, every silent sequence longer than duration gets shrinked down to duration, and the file size gets truncated to match. it's giving ✨editing✨. not me changing your file's whole life 💅
• -t <threshold>, --threshold=<threshold> — threshold is a percentage value relative to the maximum (absolute) sample value. any sample whose value is under the threshold you gave is considered silent. for example, a value of 2 means every sample with an absolute value under 2% gets treated as a silent sample. default value is 0 💀
• -v, --verbose — show more detailed info. the way i need the details 📝
• -V, --version — show version and exit. periodt.

---

🌈 FORMATS 🌈

the following modifiers are provided, and they are iconic:

• j — value is interpreted as milliseconds ⏱️
• m — value is interpreted as minutes 🕰️
• s — value is interpreted as seconds ⏳
• b — value is interpreted as bytes 💾
• k — value is interpreted as kbytes (1024 bytes) 🧚
• M — value is interpreted as megabytes (1024 kbytes) 🚀

in either case, the values you specify get rounded to get an integer number of samples. so like, math happens, don't worry about it 🔥

---

😭 BUGS 😭

tests has been done only with 44100 Hz 16 bit stereo files, though it may work with mono/stereo 8/16 bits files.

translation: it's only been tested on the one combo. it might work elsewhere but that's giving "we don't know" energy 🙈
