Dayton Audio RS75T-8 3″ Reference Full-Range Driver Truncated Frame

The Dayton Audio Reference Series sets a new standard of value in high-performance loudspeaker drivers. Incorporating a low-distortion motor system with a copper ring, a copper cap, and an aluminum phase plug, the RS75T-8 can outperform “boutique” drivers that cost several times the price. The driver’s truncated frame makes it ideal for line arrays and ultra-compact MTM designs requiring minimal driver-to-driver spacing. Its low-distortion characteristics and smooth response provide exceptional clarity, detail, and dynamics. Features a black anodized cone, heavy-duty 4-hole cast frame, low-loss rubber surround, and gold terminals.

SparkFun Thing Plus – ESP32 WROOM

The SparkFun ESP32 Thing Plus is the next step to get started with Espressif IoT ideations while still enjoying all the amenities of the original ESP32 Thing. Espressif’s ESP32 WROOM is a powerful WiFi and Bluetooth MCU module that targets a wide variety of applications. At the core of this module is the ESP32-D0WDQ6 chip which is designed to be both scalable and adaptive. To make the Thing Plus even easier to use, we’ve moved a few pins around to make the board Feather compatible and it utilizes our handy Qwiic Connect System which means no soldering or shields are required to connect it to the rest of your system. A JST connector to plug in a LiPo battery.

SparkFun Qwiic MP3 Trigger

Sometimes you just need an MP3 to play. The SparkFun Qwiic MP3 Trigger takes care of all the necessary requirements, all you need to do is send a simple I2C command and listen to whatever is on your micro SD card. The contents of the microSD card appears as a jump drive. Simply plug in the Qwiic MP3 Trigger and you’ll be transferring MP3s, no need for drivers and no need for WAV or Vorbis conversion. Your supplied speaker is boosted by a Class-D mono amplifier capable of outputting up to 1.4W making it capable of being incredibly loud. Volume is software selectable between 32 levels.

White Noise

White Noise can be used by all audiences in a variety of ways throughout our daily lives. Whether you’re trying to work, study, relax, or even sleep. Offices can be either too quiet or too noisy. White noise makes it impossible to concentrate. Sound affects many areas of the brain and has an undeniable effect on the body. A good way to test if a particular sound is relaxing to you is to check your pulse, if it slows down, then you have found the sound that is calming you. Keep listening to it and you will relax, reaching a state of increased calmness and reducing your levels of anxiety, stress, or anger.

Wave Packet

In physics, a wave packet is a short burst of localized wave action that travels as a unit. A wave packet can be analyzed into, or can be synthesized from, an infinite set of component sinusoidal waves of different wavenumbers, with phases and amplitudes such that they interfere constructively only over a small region of space, and destructively elsewhere.Each component wave function, and hence the wave packet, are solutions of a wave equation. Depending on the wave equation, the wave packet’s profile may remain constant or it may change while propagating.

White Noise

Thus, random signals are considered “white noise” if they are observed to have a flat spectrum over the range of frequencies that are relevant to the context. For an audio signal, the relevant range is the band of audible sound frequencies (between 20 and 20,000 Hz). Such a signal is heard by the human ear as a hissing sound. In music and acoustics, the term “white noise” may be used for any signal that has a similar hissing sound. It is sometimes used analogously in nontechnical contexts to mean “random talk without meaningful contents”.

Microphone

A microphone is a device a transducer that converts sound into an electrical signal. Microphones are used in many applications. They are also used in computers for recording voice, speech recognition, VoIP, and for non-acoustic purposes such as ultrasonic sensors or knock sensors.

Electret microphone is a type of electrostatic capacitor-based microphone, which eliminates the need for a polarizing power supply by using a permanently charged material. Unlike other condenser microphones, electret types require no polarizing voltage, but they normally contain an integrated preamplifier, which does require a small amount of power.

SparkFun Sound Detector

SparkFun Item: SEN-12642

The SparkFun Sound Detector is a small and very easy to use audio sensing board with three different outputs. The Sound Detector not only provides an audio output, but also a binary indication of the presence of sound, and an analog representation of its amplitude. The 3 outputs are simultaneous and independent, so you can use as many or as few as you want at once.

The envelope output allows you to easily read amplitude of sound by simply measuring the analog voltage. Gain can be adjusted with a through-hole resistor, to change the threshold of the binary output pin as well.

SparkFun Qwiic MP3 Trigger

Sometimes you just need an MP3 to play. Whether it’s a theme song as you enter the room or a power song when you are working out. The SparkFun Qwiic MP3 Trigger takes care of all the necessary requirements, all you need to do is send a simple I2C command and listen to whatever is on your micro SD card. Utilizing our handy Qwiic system, no soldering is required to connect it to the rest of your system. However, we still have broken out 0.1″-spaced pins in case you prefer to use a breadboard.

When a USB-C cable is connected to the Qwiic MP3 Trigger the contents of the microSD card appears as a jump drive. Simply plug in the Qwiic MP3 Trigger and you’ll be transferring MP3s. Sound output is provided via a 3.5mm headphone jack or poke-home connector allowing an external speaker to be connected without soldering.

We’ve written an extensive Arduino library to make MP3 playing over I2C a breeze. Play tracks, change volume, play next/previous, check if track is playing, stop play, change EQ, and change I2C address are all supported.

  • 3.3V
  • Volume, EQ setting, and I2C address settings stored in non-volatile memory and loaded at each power-on.
  • microSD supports 128MB to 32GB cards.
  • Trigger pins 1, 2, 3, and 4.
  • Up to 255 tracks can be loaded onto the SD card and triggered via the I2C interface.
  • USB-C Connector.
  • Qwiic Connector.

To be, or not to be, that is the question: Whether ’tis nobler in the mind to suffer The slings and arrows of outrageous fortune, Or to take Arms against a Sea of troubles, And by opposing end them: to die, to sleep No more; and by a sleep, to say we end The heart-ache, and the thousand natural shocks That Flesh is heir to?

Wave

In a wave is a propagating dynamic disturbance of one or more quantities, sometimes as described by a wave equation. In physical waves, at least two field quantities in the wave medium are involved. Sound waves are variations of the local pressure and particle motion that propagate through the medium.

Sine Wave

To the human ear, a sound that is made of more than one sine wave will have perceptible harmonics, addition of different sine waves results in a different waveform and thus changes the timbre of the sound. Presence of higher harmonics in addition to the fundamental causes variation in the timbre, which is the reason why the same musical note played on different instruments sounds different.

Rotary Switch – SparkFun Rotary Switch Breakout

This is a single pole, 10 position rotary switch able to select up to 10 different states in a durable package. Unlike our other rotary switch, this model is much more robust and capable of handling larger currents and voltages. Though this switch requires you to use 11 pins and is not breadboard friendly we do offer a breakout board to provide easier access to its capabilities.

This is the SparkFun Rotary Switch Breakout, a very simple board designed to easily provide you access to each pin on our 10-position rotary switches. This breakout allows you to easily add a rotary switch to your next project without having to worry about attaching its unique footprint to a custom board or solderless breadboard. All you need to do is solder the 10-position rotary switch into the breakout and each pin will become available for breadboard or hookup wire compatibility.

Attack & Decay

——

This assumes a conventional ADSR where the sustain continues at the same level as the decay, till the release ramps to 0. The most common kind of envelope generator has four stages: attack, decay, sustain, and release (ADSR). Set the attack and decay levels of the ADSR. Attack is the time taken for initial run-up of level from nil to peak, beginning when the key is pressed. Decay is the time taken for the subsequent run down from the attack level to the designated sustain level.

In the typical synthesizer, the Attack stage begins when a key is pressed. The Attack stage usually offers control of duration that is, the amount of time it takes to ascend to a high voltage level after the key is pressed. When used to modulate a VCA’s level, this allows for everything from very sudden, abrupt note onsets to slow swells that gradually fade in from nothingness. VCAs have many applications, including audio level compression, synthesizers and amplitude modulation.

After the Attack stage has reached its end, the highest point in the envelope’s cycle, the Decay stage commences. The Decay stage also offers definable duration: in this case, the amount of time it takes to fall from this high level. By using moderate Attack and Decay times and a relatively low, one can create sounds that begin with a swelled attack: a sound that increases in volume, decreases in volume, and then settles in at a low, continuous volume.

Envelope Music

In sound and music, an envelope describes how a sound changes over time. It may relate to elements such as amplitude (volume), filters (frequencies) or pitch. For example, a piano key, when struck and held, creates a near-immediate initial sound which gradually decreases in volume to zero. Envelope generators, which allow users to control the different stages of a sound, are common features of synthesizers, samplers, and other electronic musical instruments. The most common form of envelope generator is controlled with four parameters: attack, decay, sustain and release (ADSR).

A Simple ADSR Envelope Generator

This implementation has separate update and next methods, where next interpolates values between each update. The normal way to use this would be with update in update control, where it calculates a new internal state each control step, and then next is in update audio, called much more often, where it interpolates between the control values. This also allows the ADSR updates to be made even more sparsely if desired, eg. every 3rd control update.

Template Parameters

Control Update Rate: The frequency of control updates. Ordinarily this will be control rate, but an alternative (amongst others) is to set this as well as the lerp rate parameter to audio rate, and call both update and next in update audio. Such a use would allow accurate envelopes with finer resolution of the control points than control rate.

Lerp Rate: Sets how often next will be called, to interpolate between updates set by control update rate. This will produce the smoothest results if it’s set to audio rate, but if you need to save processor time and your envelope changes slowly or controls something like a filter where there may not be problems with glitchy or clicking transitions, lerp rate could be set to control rate (for instance). Then update and next could both be called in update control, greatly reducing the amount of processing required compared to calling next in update audio.

Oscil Sine Wave

Oscil plays a wavetable, cycling through the table to generate an audio or control signal. The frequency of the signal can be set or changed with frequency, and the output of an Oscil can be produced with next for a simple cycling oscillator, for a particular sample in the table.
