💖 C2DEC — codec2 testing framework 💖

okay bestie, welcome to c2dec, a User Commands classic from the codec2 universe. it's the codec2 testing framework and honestly? she's iconic. let's get into it 🎀

✨ NAME ✨

c2dec — the codec2 testing framework. that's the whole vibe. 💅

🌸 DESCRIPTION 🌸

It's a Codec2 test and evaluation program. literally what it says on the tin, no cap. it tests. it evaluates. it's giving main character energy in the codec2 friend group 🦋

⭐ USAGE ⭐

c2dec 3200|2400|1600|1400}1300|1200 InputFile OutputRawFile [OPTIONS]

okay so yes, that } in the middle there is exactly how it's written in the manual. not me fixing it, not you fixing it. we leave her alone. periodt. 🙈

so you hand her a bitrate from that lineup, an InputFile, an OutputRawFile, and then however many OPTIONS you feel like sprinkling on top ✨

💅 OPTIONS 💅

• --help — shows the help and then dips. that's it, that's the whole job. 👑
• --ber — set the bit error rate. it takes a float, so decimals are welcome here, bestie 🍓
• --startbit — sets the start bit. give it an integer. 🔢
• --endbit — sets the stop bit. also an integer. ngl she's the sibling of --startbit, they come as a set 🫶
• --berfile — specify the berfile. that's a file name string in case you were wondering. 📄
• --natural — use natural binary code. and yes, the default is gray code, so if you don't pass this flag, gray code is what you're getting. no takebacks ✨
• --dump — specify the dump file. yep, a file name string again. 🗂️

and then, the actual moment: it decodes a file of bits to a file of raw speech samples using codec2. like. bits in, raw speech samples out. she ate and left no crumbs 🔥👑
