Sampler for an intelligent cable or cable adapter

A method to process audio within an analog audio cable that includes a first plug configured for connection to an instrument or a microphone, a middle cable portion, and a second plug configured for connection to an output device, the method comprising:

• converting, using an analog-digital converter, within any one or more of the first plug, the middle cable portion, and/or the second plug of the analog audio cable, the audio signal to a digital signal, the audio signal produced by an instrument or a microphone;
• receiving, using a microcontroller, one or more audio samples from an app on a computing device and storing the one or more audio samples in a memory;
• determining, using a digital signal processor in operable communication with the microcontroller and the memory and configured to receive the digital signal, one or more audio characteristics of the digital signal and one or more of:
• generating an audio output signal based at least on:
• an audio sample of the one or more audio samples, and at least one of the one or more audio characteristics of the digital signal;
• and
• generating an audio output signal based on:
• at least one of the one or more audio characteristics of the digital signal, and an input from a synthesizer, wherein the synthesizer is located within any one or more of the first plug, the middle cable portion, and/or the second plug;
• and
• converting, using a digital-analog converter within any one or more of the first plug, the middle cable portion, and/or the second plug, the audio output signal to an analog signal.

An analog audio cable comprising:

• a first plug configured for connection to an instrument or a microphone,
• a middle cable portion, and
• a second plug configured for connection to an output device,
• wherein any one or more of the first plug, the middle cable portion, and/or the second plug comprises:
• an analog-to-digital converter configured to convert an audio signal to a digital signal, the audio signal produced by an instrument or microphone;
• a microcontroller configured to receive one or more audio samples from an app on a computing device and store the one or more audio samples in a memory;
• a synthesizer;
• a digital signal processor in operable communication with the microcontroller and configured to receive the digital signal and determine one or more audio characteristics of the digital signal, the digital signal processor further configured to perform one or more of:
• generate an audio output signal based at least on:
• an audio sample of the one or more audio samples, and at least one of the one or more audio characteristics of the digital signal;
• and
• generate an audio output signal based on:
• at least one of the one or more audio characteristics of the digital signal, and an input from the synthesizer;
• and
• a digital-analog converter configured to convert the audio output signal to an analog signal.
