I will not go much into detail, but out of curiosity I wanted to understand more about the wav file format and found a great source.Ī wave file contains a header containing important information for playing the audio file (such as frames per second, bits per sample, num of channels, etc.). Wohoo yes that sounds very easy, but doing it for the first time, it can get very interesting.īefore I dive into the challenge itself let’s see how the wav format looks like.

Sonic Visualiser is available as freeware (GNU license) for Linux, Mac and Windows.When I googled for flags or secret texts in audio files, I mostly found recommendations as: (1) Use Audacity or Sonic Visualiser, (2) check the waveform and spectrum for hints, (3) LSB might have been used to hide text or (4) maybe infra- or ultrasound range is used to transmit a secret text.

Several serious crashing, deadlock, and data corruption bugs have been fixed.

Several widget layout bugs on OS/X have been fixed.

The vertical black lines dividing segments in the time value layer’s segmentation plot style are now optional.

You can now switch layers by clicking on the spare area at the left end of the pane that is also used for the current pane indicator.

SV will take into account RDF plugin descriptions, if available, in order to make somewhat better decisions about display of plugin outputs (for example, placing segmentation data into a layer with segmentation plot type).

Alignment using the MATCH plugin is faster on OS/X than before.Spectrogram display is now faster in many circumstances.Visualisation of very dense colour plots (such as spectrograms calculated by plugins) is substantially faster in this release.The previous default is still available as a preference. The spectrogram has somewhat improved graphical scaling, and this is now the default (being much faster than the 4x oversampled method).There is a new Activity Log window with a (purely informative) list of events and user interactions that happen while SV is running.

Using a MIDI device should give better timing than using the PC keyboard.

If a time value or note layer is current it will be used for insertion (giving a value equal to the pitch class, or the played note, respectively) otherwise an existing or new time instants layer will be used just as it is when inserting instants using the PC keyboard.

You can now insert time instants, time values, and notes using a MIDI device during playback.Also, the binary packages for this release have been built with Qt 4.5 instead of 4.4, offering better performance and platform integration. This release has a few new features and a substantial number of bug fixes over the previous version 1.4. Chris Cannam has released version 1.5 of Sonic Visualiser, an application for inspecting and analysing the contents of music audio files.
