Odd harmonics are harmonics that appear as odd multiples of the fundamental frequency. For example, in a note with the fundamental frequency of A4 (440Hz), the odd harmonics could be 1320Hz (3 times), 2200Hz (5 times), 3080Hz (7 times), and so on. These harmonics can give the sound a ‘rough’ or ‘sharp’ texture, often making the timbre of an instrument ‘sharper’.

On the other hand, even harmonics are harmonics that appear as even multiples of the fundamental frequency. In the same note of A4, even harmonics could be 880Hz (2 times), 1760Hz (4 times), 2640Hz (6 times), etc. Even harmonics typically provide a ‘smoother’ and ‘more harmonious’ feel.

Condenser microphones are divided into FET, Tube, and Handheld types.Among them, tube microphones are perceived as high-end microphones.Of course, not all tubes are automatically good, but there are definite advantages that tubes can offer. The characteristics of vacuum tubes can be broadly classified into four categories. Let’s take a closer look.

Many people face difficulties when selecting a microphone. This is often due to a lack of understanding of how to read specifications and what criteria define a good microphone. Some recommend microphones with phrases like ‘microphones that suit men well’ or ‘microphones that are good for thin vocals,’ but these are not actually good directions for evaluating a microphone.

People often ask about ‘the best microphone for a certain type of voice,’ but this is subjective and varies according to personal preference. Of course, certain microphones might emphasize or weaken specific frequency bands (often referred to as their ‘color’), but this doesn’t mean they are a perfect match for every situation.

Dynamic Microphone Dynamic microphones capture sound using the principle of electromagnetic induction. The diaphragm moves in response to sound vibrations, and this movement causes an attached coil to move within the field of a permanent magnet. This movement generates an electrical signal within the coil, reflecting the sound vibrations. In other words, they do not require phantom power (external power supply).
Condenser microphones capture sound using the principle of capacitance. When sound moves the diaphragm, it alters the distance between the diaphragm and a backplate, changing the capacitance of the capacitor. This change is manifested as a voltage variation, which is then amplified and converted into an audio signal through amplifiers and other electronic circuits.
