I also wonder if (if you're using the wrong input) you may also be encountering an impedance mismatch - the Hama mic is rated at 600 Ohm impedance your sound card's mic input will be rated at anything between 600 Ohm - 1 kohm and (hopefully) be balanced the Line In is typically unbalanced and has an impedance of ~10 kohm (can be anything up to 1 Megaohm). By contrast, a Shure SM58 Beta goes from 50Hz to 20kHz and generally has a far higher build quality and sensitivity which results in a higher dynamic range in your recordings before you reach the noise floor). Hama themselves rate it as "90Hz – 10kHz (frequency response), impedance of 600 Ohm and sensitivity of -76dB".
(dBU = deciBels Unloaded dBV = deciBel volts dBm = deciBel milliwatts)Īnother consideration is your microphone - unfortunately, it's not great.
(Delving into signal theory a bit, because it is relevant: the industry reference level is 0.775 Volts, aka 0 dBV Professional Line level is ~1.25 V or +4 dBm Consumer Line Level is about 0.316 Volts or -10 dBV Mic level is usually ~40 dB quieter than pro level (this can vary though), between -40 to -56 dBm.) If you're using the wrong input you will likely hear nothing (or a remarkably quiet sound, even if you shout at the mic from 2cm away). Are you using the correct input on your sound card? If using an integrated sound card, you will usually have Line Out (speakers), Line In and Mic In.
