Description:

Buzz. Beep and bloop. We’re high on the lo-fi sounds of “old-school” games, toys and terminals and the Mainframe Bit Crusher takes us back in time to when Pac Man and Donkey Kong ruled the arcades, to when the Commodore 64 was high tech.

It provides sample rate reduction ranging from 48kHz to 110Hz. A little background… the sample rate is the number of times per second that a sample or snapshot of an analog signal is taken. For example, CDs (remember them?) had a sample rate of 44.1kHz which means that the original analog signal is sampled 44,100 times per second.

The sample rate defines the frequency range that can be reproduced while maintaining good fidelity. When the sample rate is reduced the quality of the audio is degraded and aliasing occurs. Aliasing means audible artifacts created when higher frequencies are sampled at an inadequate rate and the result is distortion. The Mainframe’s sample rate range is wide enough to take you from sounds that are quite pristine to sounds that are unrecognizable when compared to the input signal.

It also provides bit crushing ranging from 24-bit to 1-bit. What does that mean? Bit crushing is bit depth reduction. Back to our CD example… CDs used a 16-bit bit depth meaning that each of its samples was represented by 16-bits of information. Higher bit depths can accurately represent a greater dynamic range while bit crushing increases the number of sampling errors and creatively degrades the sound to bring us back to those nasty “old school” sounds we love.

The Mainframe’s selectable High/Low/Band-Pass filter lets the user shape the artifacts of the bit crushing and sample rate. Another very cool feature is its Sample Rate Tuning Mode where the pedal analyzes your input signal in real-time and sets the sample rate to match the pitch of your signal, or a set interval above your signal. This allows you to set the sample rate to match the key of a song, or it will continually adjust the sample rate based on what you play!

QUICK SPECS:
• Sample Rate Reduction ranging from 48kHz to 110Hz
• Bit Depth Reduction ranging from 24-bit to 1-bit
• Selectable High/Low/Band-Pass filter to shape the artifacts of the bit crushing and sample rate reduction

• Secondary knob parameters allow you to fine-tune the Mainframe’s effect.
• High quality buffered bypass and silent switching

    I love these pillows
    Size: Queen (Pack of 2)
    These are so comfy. I love them. They have made my life so much better. I have really bad insomnia. I was also getting neck pains from my old pillows. These are just the best for sitting up and sleeping. I can not tell you how much these changed my life. They are worth a shot if you are looking for something. 10 out of 10.

However AI indicated most pillows are constructed with two layers because of it is all dow it will be flat ... anyway the pillows will be tested after tomorrow as they recommend to leave it for one day before using it.. To be continued later

    Great for side sleepers
    It always seems hard to find the perfect pillow when you’re a side-sleeper. This one is great. It comes compressed so you will want to allow some time for it to fully fluff back up. The cover is soft and smooth. I love that it isn’t overstuffed. It provides gentle support and a lot of comfort. I was worried it may be too warm since it is polyester, but it is very breathable and I have not had any issues with feeling overly warm on it. It fits a standard size pillow case. It’s not overly stuffed like some other pillows I’ve tried that were specifically for side-sleepers. I think this world be a great pillow for any sleeping position, really. I wasn’t expecting to love a pillow this affordable, but it gets the job done and I get a good night of sleep. I’ll be purchasing some more for our guest room.

    Incredibly Comfortable and Supportive — My New Favorite Pillow!
    I wasn’t expecting to love this pillow as much as I do, but the DIORIS large sleeping pillow really exceeded my expectations. From the first night, I noticed a difference in the way my neck and shoulders felt in the morning—less tension, better alignment, and overall more restful sleep. The fill is just the right balance between plush and supportive. It doesn’t flatten out during the night, which is a problem I’ve had with other pillows, especially those that come overstuffed or too soft. This one holds its shape well but still has that cozy, cloud-like feel when you lay your head on it. I’m a side and back sleeper, and this pillow works beautifully in both positions. It’s also large enough that I don’t feel like I’m falling off it during the night, but not so big that it takes over the whole bed. One suggestion: if you’re picky about loft, you might want to give it a gentle fluff or adjust the fill before your first night. But honestly, I didn’t need to do much—it was pretty much perfect out of the bag. Highly recommended if you're looking for a high-quality, comfortable, and generously sized pillow that supports a great night’s sleep!

    Hotel like pillow
    These pillows were a pleasant surprise. I bought the set for our guest room but ended up keeping them for our own bed after trying them out. They feel incredibly soft yet still provide enough support to keep my neck from feeling stiff in the morning. I sleep on my side and back, and these work great for both positions. My spouse, who usually runs hot at night, said they stayed cool and breathable. The material feels high quality, and I love that they’re machine washable without losing their shape. They fluffed right back up after drying. If you're looking for that plush hotel-pillow feel with everyday practicality, this set really delivers.
