Yes, no DC as there will be no air gap. You might not have to derate, as higher frequencies will help. However, I assume we are talking about instruments rather than hi-fi. It was common in the past for radio amateurs to use power transformers as AM modulation transformers, although only a limited frequency range (up to about 3kHz) was needed. P
Audio Transformer, its Types and Impedance Ratio
https://circuitdigest.com/tutorial/audio-transformer
An Audio transformer with Step-up feature will step up the voltage or the current level to drive a load across it. Same happens for the Stepdown transformer too. It converts the voltage from higher to lower with the increased current output. The audio transformer also provides impedance matching specifications. When the output of one circuit or device is …

In a similar fashion (as explained above), audio transformers are used to change the impedance between the microphones and input amplifiers so that signal power is not reduced. 2. DC Blocking Typically the output amplifier’s AC signal is very low and is superimposed on the high voltage DC signal.
Transformers - When to use and how does it work?

Audio Transformers. Audio transformers can: 1) Step up (increase) or step down (decrease) a signal voltage; 2) Increase or decrease the impedance of a circuit; 3) Convert a circuit from unbalanced to balanced and vice versa; 4) Block DC current in a circuit while allowing AC current to flow; 5) Electrically isolate one audio device from another. While transformers are useful in …

To go with Kchristes comment, audio transformers operate at much lower voltages than power transformers. However, audio transformers will have a higher DC resistance than power transformers, so you probably won't damage anything by hooking it up to DC. But it also depends on the resistance of the coil. Simply ohm it out to verify.
