Choose the capacitor dielectric depending on the expected use for the filter. NP0 (aka C0G) ceramics can be used for low values.

Increasing capacitance or resistance reduces the cutoff frequency and vice versa.Ĭapacitors used in filter circuits should be polyester, Mylar, polypropylene, polystyrene or similar. This provides a -3dB frequency of 1.59kHz in most cases. I have normalised the frequency setting components to 10k for resistors, and 10nF for capacitors. There is some duplication - the original article was written some time ago, and it was considered worthwhile to include some of the basic info in both articles.įilters are used at the frequencies where they are needed, so the filters described here need to be recalculated. If you are not already familiar with the concept of filters, it might be better to read the article Designing With Opamps - Part 2, as this gives a bit more background information but a lot less detail than shown here. In some cases, this doesn't represent a problem if the ringing is outside the audio band, but can be an issue for filters used in crossover networks (for example). While at first look this might be thought rather pointless, like all circuits that have been developed over the years it often comes in very handy.įilters also affect the transient response of the signal passing through, and extreme filters (high order types or filters with a high Q) can even cause ringing (a damped oscillation) at the filter's cutoff frequency. There is one class of filter called 'all-pass' that does not affect the response, only phase. All filters introduce phase shift, and (almost all) filters change the frequency response. There is a wide range of filter circuits, each with its own set of advantages and disadvantages.

Record new audio file from a microphone or another sound source. Or, use build-in CD burner to burn your recordings to CD! You can use the build-in CD ripper to copy all or some of your music tracks from your personal CD collection. It is easy to convert an audio file from one format to another. It includes a click and crackle filter for cleaning vinyl records, a noise filter for cassette-tape recordings, and an equalizer to enhance the sound quality of all recordings.Ĭool Record Edit Pro supports a wide range of audio formats, such as MPEG (MP3, MP2), WAV, Windows Media Audio, Ogg Vorbis, Audio Tracks and Dialogic VOX. The Editor allows you to perform various operations with audio data such as displaying a waveform image of an audio file, filtering, applying various audio effects and more. The software helps protect your valuable recordings-just set the sound source, the recording quality, and volume, then start recording. Cool Record Edit Pro helps you transfer tapes, LPs, live performances, Internet radio, TV, DVD, or any other sound source to your hard drive.
