IHSIM vs ASL Signcaster

IMPAIRED HEARING SIMULATION (IHSIM) This app performs separate simulations of acoustic hearing loss and cochlear implant processing. These simulations process the audio input from the iOS device in real-time. In the acoustic hearing loss simulation, a user can achieve custom spectral filtering based on a listener's audiogram. Six presets are also provided of common audiogram functions. A dynamic range compressor is included, along with a frequency smearing algorithm to flatten the signal's spectrum and perform subtle pitch modulation. In the cochlear implant simulation, a filterbank vocoder is implemented. The number of frequency bands is selectable, along with the carrier signal (noise or sine wave vocoder), the frequency divisions (Logarithmic or Greenwood function), and the overall bandwidth. Electric-only and "hybrid" acoustic-electric cochlear implants are modeled. Several monaural and binaural stimulation options are selectable. HEADPHONES AND SENNHEISER SMART AMBEO HEADSET This app was created as part of the Sennheiser Developers Program for the Smart AMBEO Headset. The app is capable of processing a stereo input signal, taking advantage of the "augmented reality" features of the headset. The app is also fully-functional using a conventional set of headphones with a mono microphone input. It is highly recommended to use headphones of some type with the app. FOR RESEARCH AND EDUCATIONAL PURPOSES The intended use of the app is for auditory perception research. The app may have additional educational purposes related to hearing loss. The app should not be used for medical purposes. INFORMATION Resources related to the app are available at: hackaudio.com

Do you want to learn ASL, but in a fun, engaging way that doesn't feel like a worksheet? Or do you want to help your young child learn and practice ASL, but they can't read yet, so many ASL apps that require reading don't work for you? ASL Signcaster is designed to teach ASL to match how children learn language - from context, play, and engagement with families. You don't need to know English or know how to read in order to learn early ASL words and grammar with Signcaster. Cast spells and learn what the ASL sign for each one is. Click on the spell in the spell book, then click somewhere in the world to cast the spell. Cast a boat spell, and make a boat appear. Change the boat's colors, make it hop or dance, or make it disappear! Kids love to create silly scenes that they can come back to again and again, like a forest of bouncing blue bananas, or dancing flowers, or running boats. Learn ASL through play and research-backed language learning strategies, designed by Linguists, Deaf actors, artists, and game designers, ASL interpreters, and our foundation-funded indie game team based out of Pittsburgh, Pennsylvania.
