Abstract: An apparatus and system for generating sound and methods for making and using same. A motor-driving signal with an audio signal component is applied to a motor. When driven by the motor-driving signal, the motor thereby can generate a sound that corresponds to the audio signal component. An exemplary sound can include high-quality audio content such as music, speech, or a combination thereof. The motor-driving signal can be produced by modulating a carrier signal with the audio signal and can enable a vibration in the motor for generating the sound. When associated with a mobile platform, the motor can be configured to generate the sound and enable the mobile platform to move. Advantageously, without installing separate audio system hardware, the mobile platform thereby is capable of conveying information that is audible and comprehensible to a human. Communication efficiency between the human and the mobile platform can thus be improved.

Abstract: In an example context of identifying live audio, an audio processor machine accesses audio data that represents a query sound and creates a spectrogram from the audio data. Each segment of the spectrogram represents a different time slice in the query sound. For each time slice, the audio processor machine determines one or more dominant frequencies and an aggregate energy value that represents a combination of all the energy for that dominant frequency and its harmonics. The machine creates a harmonogram by representing these aggregate energy values at these dominant frequencies in each time slice. The harmonogram thus may represent the strongest harmonic components within the query sound. The machine can identify the query sound by comparing its harmonogram to other harmonograms of other sounds and may respond to a user's submission of the query sound by providing an identifier of the query sound to the user.

Abstract: Technologies for cryptographic protection of I/O audio data include a computing device with a cryptographic engine and an audio controller. A trusted software component may request an untrusted audio driver to establish an audio session with the audio controller that is associated with an audio codec. The trusted software component may verify that a stream identifier associated with the audio session received from the audio driver matches a stream identifier received from the codec. The trusted software may program the cryptographic engine with a DMA channel identifier associated with the codec, and the audio controller may assert the channel identifier in each DMA transaction associated with the audio session. The cryptographic engine cryptographically protects audio data associated with the audio session. The audio controller may lock the controller topology after establishing the audio session, to prevent re-routing of audio during a trusted audio session. Other embodiments are described and claimed.
