This video demonstrates screen capture tools designed to improve performance.
 Wave-form (beat-resolution), Tuner, peak meter, beat mapped timeline and video, syncronized to a score.
Having the performance sync'd to a score allows one to easily identify errors, notes that sound out-of-tune or out-of-balance; offering,  as well, visual identification of performance gestures that are awkward/inefficient/strained.  

The same techniques can be applied to professional recordings with the visualizations aiding as tools for comparison of ornaments and artistic elements (color, volume, articulation, rubato, tempo modulation, fingering and orchestration).

By comparing errors and interpretative differences between performances, one can triangulate (more/less/exactly) to refine the interpretation, identify and systematically eliminate idiosyncratic elements and recurrent errors.  By comparing similarities across several reference performances, one can make loose assumptions about the (off the page) intent of the composer, esp regarding phrasing, relative cadence weight and tempo.   

By comparing one's own performances to reference recordings it is easy to identify idiosyncratic elements, wrong notes, bad subdivisions, and to glean ideas about dynamics, color, style and phrasing. 
Take lessons from a master.  Let your favorite recordings be your teacher.  Synchronize your sheet music to your favorite recording and play unison duets with a master.  Then play along with the video with the sound off. 
Your self-recordings the mirror by which you refine your own playing and evaluate progress.  The practice of recording yourself, and listening back (every day) will  allow you to notice small changes in your recording setup like recording to a smartphone or recording to a computer, with the same interface and microphones.

here's a performance of the same piece from the day before I recorded this
