PC Sound Card Oscilloscope

I would like to buy a Microphone and either #1. an oscilloscope or #2. sound oscilloscope software. For hobby purposes, I would like to sample different sounds & view the various sound waves studying the amplitudes & frequencies. Do you have a product that would meet these criteria?

As a result many electronics hobbyist made their own scope. The popular electronics magazines in the sixties and seventies were full of scope designs almost always based on vacuum tubes. This period was closed in 1975 when the Dutch electronics magazine Elektuur (in the rest of the world known as Elektor) published their fully transistorised “Elektorscoop”. Despite all this, the purchase of the expensive cathode ray tube and Special high voltage transformer remained too expensive for many people.

The PC based Soundcard Oscilloscope receives its data from the Soundcard with 44.1kHz and 16 Bit resolution. The data source can be selected in the Windows mixer (Microphone, Line-In or Wave). The frequency range depends on the sound card, but 20-20000Hz should be possible with all modern cards. The low frequency end is limited by the AC coupling of the line-in signal. Be aware, that most microphone inputs are only mono.
