While "line level" audio is typically 1 mW into 600 Ω, and this comes out to 1.1 V p for a sine, audio is far from a sine. Even if the spec is adhered to and you only get 775 mV RMS on average, the peaks can be considerably higher than 1.1 V. It is generally good to accept and handle without distortion peaks up to ± 5 V at least. Share

https://electronics.stackexchange.com/questions/298573/understanding-voltage-levels-on-3-5-mm-audio-output
When no audio is playing, there's a voltage of about 2 mV. When I output a constant audio signal, the voltage rises initially to 0.5 V, but drops back to 2 mV after 2-3 seconds. What purpose does this 2 mV bias voltage serve? Does audio output circuitry usually contain DC blocking capacitors, or is DC blocked via some other means? audio headphones

An Overview of Audio Levels. There are three main Audio Levels that are worth knowing about: Microphone Level; Line Level; Speaker Level; The determining factor here is the voltage which runs them. Speaking into a microphone only produces a few thousandths of a volt, but loudspeakers need a whole bunch of volts to make their big magnets move. What is Mic Level?

Notice how drastically different the levels are. 1. Mic Level Microphones have comparatively small output voltages, on the order of thousandths of a volt (0.001V) ranging up to tenths of a volt (0.1V). Mic outputs can range from very low to very high depending on the mic type and design. Low-output Mics
