Tape Cassette 2 is an audio plugin that emulates the warmth, noise and character of old tape cassettes. Following up from our well received Tape Cassette 1, we’ve updated the plugin with a sleek interface and more changes under the hood too. Along with a brand new selectable Type 1 Cassette Impulse Response (IR), we’ve improved the saturation algorithm, wow & flutter engine and implemented real sampled tape noise, all which results in a wonderfully warm and more accurate vintage sound. In addition to this you now have two VU meters to monitor your audio and built in oversampling. You can easily add that classic sound to an entire track, or use directly on individual channels, for added movement, texture and warmth. Alternatively you can take it further than the material limitations of tape and push the parameters into a far more experimental soundscape, as a sound design tool. Parameters: ⁃ Saturation (+/-24dB) ⁃ Low Pass Filter (5 to 22KHz) ⁃ Noise (-80 to 0 dB) ⁃ Wow (0 to 100%) ⁃ Flutter (0 to 100%) - IR (On/Off) - Auto-Gain (On/Off) - Output (+/-24dB) Tape Cassette 2 is both a stand-alone application as well as an AUv3 plugin, meaning it works within iOS and iPadOS hosts such as GarageBand.
