characteristics than toroidal cores for single-ended tube amplifiers, with easier winding methods. Fig. 3. EI type of transformer core Based on an output power of 3.5 W, the size of transformer core has been chosen as EI 16*24 with 3.81 cm2 middle leg (or tongue) area [2]. The number of windings was then calculated [3]: w1=1200*(L)1/2=3600;

Transformers for Audio
https://sound-au.com/articles/audio-xfmrs.htm
Audio transformers use low-loss cores, but that's not the case for a mains transformer. So, while you can use a mains transformer for line-level audio, it's not recommended. Toroidal transformers are better in this respect, but that's an expensive way to get a signal transformer that will be far bigger than an equivalent 'audio transformer'.
Audio Transformer, its Types and Impedance Ratio
https://circuitdigest.com/tutorial/audio-transformer
This conversion actually happens by the two or more insulated copper wire coils (which are denoted as windings) wrapped around a magnetic iron core. Audio Transformer uses this isolation property and creates isolation between the output speakers or audio circuitry with the transformer’s input side amplifier system.

Audio Frequency (AF) Transformers work at frequencies between about 20Hz to 20kHz and are used in audio amplifier circuits, they were essential in valve (tube) designs for matching the high impedance outputs of theses amplifiers to low impedance loudspeakers, but transistor amplifiers have much less need for output transformers.
