A-law algorithm

<h2 id="comparison-to--law">Comparison to μ-law</h2>
<p>The <a href="/facts/%25CE%259C-law_algorithm/Ve8vJ6mb">μ-law algorithm</a> provides a slightly larger dynamic range than the A-law at the cost of worse proportional distortion for small signals. By convention, A-law is used for an international connection if at least one country uses it.
