Shot-for-shot r emakes of films are those which are faithful to original plots and scripts. Between-respondent agreement was the overall result from the qualitative part of the study, with no interactions by age or gender evident aside from slightly higher certainty about prior or future events in the film in male respondents. No useful deductions were made from intensity measures. Overall, it appears that pitch has fallen over time, in prosody acted for film. This part of the study comprises two strands - one being set within the context of Meyer's (1957) analogy of information theory, the other within an dimensional arousal-valence space representing emotional states. A survey was also conducted to augment the quantitative analyses, and provide a relevant perceptual counterpart to its broad scope. It employs pitch extraction and intensity estimation analyses to measure the fundamental frequency and dynamic differences in actors' utterances. Sonic Visualiser eats that.This study examines two data sets from films and their re-makes, set about 20 - 30 years apart (1930s - 1950s, and 1970s to early twenty first century), to determine whether any significant changes have occurred in actors' emotional prosody. The work Sonic Visualiser does is intrinsically processor-hungry and (often) memory-hungry, but the aim is to allow you to work with long audio files on machines with modest CPU and memory where reasonable. Sonic Visualiser is pervasively multithreaded, loves multiprocessor and multicore systems, and can make good use of fast processors with plenty of memory. Even if you have to wait for your results to be calculated, you should be able to do something else with the audio data while you wait. In this respect, Sonic Visualiser aims to resemble a consumer audio application. The user interface should be simpler to learn and to explain than the internal data structures. To facilitate ready comparisons between different kinds of data, for example by making it easy to overlay one set of data on another, or display the same data in more than one way at the same time. To provide the best available core waveform and spectrogram audio visualisations for use with substantial files of music audio data. ![]() The design goals for Sonic Visualiser are: Time-stretch playback, slowing right down or speeding up to a tiny fraction or huge multiple of the original speed while retaining a synchronised display.Įxport audio regions and annotation layers to external files. Select areas of interest, optionally snapping to nearby feature locations, and audition individual and comparative selections in seamless loops. Play back the audio plus synthesised annotations, taking care to synchronise playback with display. Import note data from MIDI files, view it alongside other frequency scales, and play it with the original audio. Import annotation layers from various text file formats. Run feature-extraction plugins to calculate annotations automatically, using algorithms such as beat trackers, pitch detectors and so on. View the same data at multiple time resolutions simultaneously (for close-up and overview). Overlay annotations on top of one another with aligned scales, and overlay annotations on top of waveform or spectrogram views. Look at audio visualisations such as spectrogram views, with interactive adjustment of display parameters.Īnnotate audio data by adding labelled time points and defining segments, point values and curves. Load audio files in WAV, Ogg and MP3 formats, and view their waveforms. Sonic Visualiser contains features for the following: ![]()
