looking at this further I don't understand why the levels show so low in players like Audacity. LPCM should be the default format. Essentially because it is lossless which is, I assume, why we use it rather than A-Law or μ-Law logarithmic amplitude compression which is usually used to fit 16 or 24-bit linear samples into an 8-bits/sample format. 73 Bill G4WJS. ------------------------------------------------------------------------------ Site24x7 APM Insight: Get Deep Visibility into Application Performance APM + Mobile APM + RUM: Monitor 3 App instances at just $35/Month Monitor end-to-end web transactions and take corrective actions now Troubleshoot faster and improve end-user experience.
