Audio Recording With a Smartphone - Wild Mountain Echoes. It seems like smartphones will do anything.
But do they make effective sound recorders? That depends on what you are looking (listening) for and what type of phone you have. Below I describe ways to record on your smartphone, with examples of products that might help. Most of this discussion is about Android phones and iPhones; tablets are for another day. There are 4 basic ways to use your phone as a recorder: The built-in microphone(s).Using a microphone plugged in through the headset port.Using a microphone plugged in through the charging port.Via Bluetooth. If you are looking to use your phone as a voice recorder, for recording personal notes, meetings, or impromptu sounds around you, then all you need is a recording app. Microphones on various models of phones vary quite a bit. Most iPhones and smart phones these days come with a TRRS port for the headphones. Because of the differences in jacks, you cannot plug in any old microphone with a 3.5mm plug and expect it to work.

For musicians, these files are getting hard to come by. I am putting up my collection of midi files for use by anyone who can use them or would enjoy them. With a few exceptions, I didn't sequence or even edit any of these. A number "2" or even "3" or higher just indicates additional copies of a file. Sometimes I liked some aspects or other better or one version had more complete or different instrumentation. Copyright Alexplorer. Procedural music generation techniques. Mitpressjournals.

Cellular automata and music. Many computer programmers are accomplished musicians; it's the rare software company that can't put together a decent house band.
However, many programmer/musicians might be unaware of an interesting area in which their vocations and avocations intersect: algorithmic music composition. Algorithmic music composition is the application of a rigid, well-defined algorithm to the process of composing music. Cellular automata (CAs) -- a class of mathematical structures that evolve over time -- present an intriguing avenue for algorithmic music composition. Computers are ideal for computing the evolutions of a cellular automaton (CA) and displaying them graphically. You can also represent the evolutions with sound, including music. An overview of cellular automata A CA consists of: A matrix, or grid, of cells, each of which can be in one of a finite number of statesA rule that defines how the cells' states are updated over time The matrix of cells can have any number of dimensions.
Figure 1. Markov chain. A simple two-state Markov chain A Markov chain (discrete-time Markov chain or DTMC), named after Andrey Markov, is a random process that undergoes transitions from one state to another on a state space.
It must possess a property that is usually characterized as "memoryless": the probability distribution of the next state depends only on the current state and not on the sequence of events that preceded it. This specific kind of "memorylessness" is called the Markov property. Markov chains have many applications as statistical models of real-world processes. Introduction A Markov chain is a stochastic process with the Markov property. In the literature, different kinds of Markov process are designated as "Markov chains". The changes of state of the system are called transitions. A discrete-time random process involves a system which is in a certain state at each step, with the state changing randomly between steps. Many other examples of Markov chains exist. Formal definition Tones: Generate a Composition.
