I've previously recounted how I was (am) unsatisfied with ExpressScribe for controlling audio playback for transcribing interviews. Because the basic functionality of the program is so straightforward (using global hotkeys to control audio playback), I was disappointed that there was no free, open-source alternative to ExpressScribe. So I'm making one.

The TranscribeSharp UI is essentially identical to the PracticeSharp UI in this preview release. Transcription-focused changes to the UI are planned.
TranscribeSharp is a program that will let you control the playback for audio files using hotkeys while you transcribe the file in another program (e.g. Microsoft Word or LibreOffice Writer). You can slow down, speed up, fast forward, rewind, pause, etc. the audio using you keyboard without ever leaving the program you are transcribing with.

The Hotkey Settings menu can be used to change between two predefined sets of hotkeys.
TranscribeSharp is in large part based on PracticeSharp by Yuval Naveh with addition of the LowLevelHooks library by Curtis Rutland. I do not consider myself a skilled programmer, and TranscribeSharp is in some sense just these two pieces of software smashed together. Without PracticeSharp and LowLevelHooks, TranscribeSharp would not be possible.
Right now, this is just a preview release. There are a few bugs, but it is a functional software solution. I wrote this to use for transcribing interviews for my dissertation, but I figured that other people may be interested in using it as well. This is a very low priority project for me, though, so please understand that. I do have a list of features that I would like to eventually add (e.g. the ability to customize the hotkeys, video playpack, an installer, and a different UI), but I have no timeline for implementing these.
TranscribeSharp is written in C# using Visual Studio 2013 and licensed under the LGPL. The full source code is available at BitBucket. If anyone is interested in helping out with bug fixes or implementing new features, just get in contact with me - I am very interested in not working on this project alone. (This was also my first time really using Git, so in future releases I intend on re-structuring the way I use the dependencies.)
To use the program, just unzip the file below and run TranscribeSharp.exe. You'll need the .NET Framework (at least version 4) installed to use it. The program should work on Windows 7 and 8 (maybe more). I hope you find this program useful.
