Danalog: Digital Music Synthesizer, Evan R. Lew

Electrical Engineering

The Danalog is a 25 key portable digital music synthesizer that uses multiple synthesis methods and effects to generate sounds. Sound varieties included three synthesis methods including FM, subtractive, and sample-based, with up to eight adjustable parameters, at least four effects, including reverb, chorus, and flange, with five adjustable parameters, and at least two note polyphony, and a five band equalizer. The user would be able to adjust these effects using digital encoders and potentiometers and view the settings on two LCD screens.

The finals project was unable to meet the original design requirements. The FM synthesis method was primarily …

Wireless Audio Bridge, Daniel L. Hodges

Electrical Engineering

Bluetooth, a wireless technology standard used to exchange data using radio transmissions, has made a significant impact on the audio technology industry, specifically the way people listen to music. This technology enables a wireless listening experience, eliminating the need for wires or cables between audio devices as previously required. Audio can transmit from a cellphone or laptop (an output device) to a pair of headphones or speakers (an input device) without any physical connection. Compared to alternative wireless listening solutions (i.e. FM transmitter, radio broadcast), Bluetooth offers greater reliability, audio fidelity, portability, and ease of use. To obtain this functionality, …

Baserock Bluetooth: Bi-Directional Bluetooth And 3.5 Mm Headphone Jack Compatibility Device, Jonathan A. Falco

Electrical Engineering

This project was proposed by a startup company from downtown San Luis Obispo called BaseRock. BaseRock sells a backpack containing subwoofers to allow the user to feel low frequencies of music. It is intended for concerts or personal use, listening to songs on an MP3. The main way the BaseRock backpack communicates with MP3s is via the headphone jack. With the introduction of the Apple iPhone 7 in September of 2016, BaseRock realized it was at a disadvantage. Millions of iPhone 7 owners and potential customers around the globe would no longer possess a headphone jack. BaseRock needs a Bluetooth-to-headphone …
