Can modem data analyzers capture modem communications from audio recordings?
Yes, with some restrictions. The recorded audio must be a high-quality recording. Distortion in frequency or amplitude can introduce errors or make the recording unusable. Refer the application note on Audio Recording and Playback for detailed information and illustrations. Connecting audio recording equipment to a phone line can destroy equipment. An interface, such as an ADM (analog data monitor) or PLI (phone line interface), is necessary to properly couple the audio and protect the equipment. The playback device is also important. It must not introduce distortion during the playback. The audio amplitude may also need to be adjusted to obtain an optimum signal for decoding. :Some audio file formats introduce loss. This is usually from compression of the data file. The file should be “CD” quality. MP3 file formats are recommended. Allied Analogic, Inc. cannot provide support for any recording equipment or software. Support is limited to the correct functioning of the data capture dev
