I have a 12 hour long audio file and know that certain inaudible "beeps" are emitted randomly. I need a software that "listens to the audio file" and identifies the time in which the beeps are emmitted.

Hello, I am an engineer and I know how to use tools to analyse sounds files. To better help you, I would yet need some more informations : - have you a sample of the "inaudible sound". I mean, even though it is inaudible for the human, a recording of it would help to analyze the data - in what formats are your input file ? - can you give some more explanations about the context of your need ? I hope we can work together. Please send me a message if you are interested. Best regards

Hello, my name is Leopoldo and I’m a musician and electronic engineer from Argentina specialized in audio and acoustics. In 2004 I started working with music in personal projects, and during my career I focused my studies in acoustics and digital signal processing. Since 2006 I have been working in music writing, recording, editing and mixing for small bands and singers, taking advantage of the expertise gained in my career. I acquired advanced technical knowledge through my diploma in Acoustics and Electroacoustics, and I expanded my experience during my research at the CINTRA Acoustics Research Center. I have worked with audio signals processing for more than 3 years developing active noise control systems for car interiors, taking care of both the acoustic aspects of the problem and microcontroller programming. I have developed acoustic systems simulations in Matlab, acoustic parameters measurements with Dirac and SiaSmaart Live, and audio signal processing with Nuendo and Cubase. I have also designed and built vacuum tube based analog signal processors for electric guitar. I have a home studio fitted with professional equipment (Presonus soundcard, Mackie and Behringer studio monitors, Studio Project and Shure microphones, etc). I am very passionate about my work, and I believe good communication and compromise to goals are the key to ensure my clients satisfaction. I look forward to hearing back from you and hope we can work together. Kind regards, Leopoldo Budde
