Deep Dive: μ-law (Mulaw) Audio Encoding

μ-law is a companding algorithm used in telephony (North America, Japan). It compresses 14-bit linear PCM into 8-bit samples, giving better quality for quiet sounds at the expense of loud sounds.

Mulaw Byte Structure:

Bit:    7    6    5    4    3    2    1    0
      +----+----+----+----+----+----+----+----+
      | S  |    Exponent   |     Mantissa     |
 +----+----+----+----+----+----+----+----+

🐎 Going Cowboy

Definition

Going cowboy is when engineers bypass established processes, guardrails, or compliance gates to push code or infrastructure changes directly — often under pressure, urgency, or just to "get it done."

While it might seem faster in the moment, in a regulated environment (like finance) this creates high risk, including:

• ❌ Bypassing required reviews (e.g., four-eyes principle).
• ❌ Skipping compliance or audit checks.
• ❌ Creating blind spots for regulators and security teams.
• ❌ Potential fines or legal consequences if untracked changes are discovered.
