Answers.Text: +1 That video is a really good illustration of the loudness wars problem. How many recordings have been destroyed with this kind of treatment? There's no telling.

Answers.Text: Please do not destroy the beautiful sound of the instruments with compression. Classical music is some of the only music that still has a large dynamic range, and it's very very very nice.

Answers.Body: <p>The real answer: make sure your input level is OK every time you record something. Make sure that the loudest passages are just hitting the head (I try getting to > -1dB FS while not clipping.) , so the soft passages have enough detail. Also remember that dynamic range is a musical ingredient in classical music, even between different pieces. If things are soft in the hall, you don't want them as loud in your recording as things that are loud in the hall, you will lose a bit of musicality.</p>
  
  <p>So: never ever compress classical music to solve your dynamic range problems, unless you use it for professional broadcasting purposes only. (And even then, don't compress the master, but use compression in the broadcasting chain.)</p>
  
  <p>Instead, if you still want to fix things because you are turning the volume up and down between the pieces: slightly adjusting the overall levels of the pieces a bit is in many occasions the right thing to do. To do this, edit all pieces so that they fade in and out on the beginning and the end. (With a piece, I mean, if you record a Beethoven symphony, those 4 movements are related, so only fade the beginning of the first movement in, and the applause at the end of the last movement out. Don't fade in between the movements and don't adjust the volume for the individual movements!) If you do this, you can make slight adjustments to the overall level of the pieces. Don't normalize to 0dB FS though, and don't make the changes too big. A few (e.g. 3) dB could just be enough to solve your problem.</p>
  
  <p>If you want to go this path, make sure you always record in 24 bits so you have more detail in your audio if you increase the volume in the master. (Sample rate is of less importance, but to record in 96KHz or in 88.2KHz is always good.)</p>
  
  <p>My personal tips:</p>
  
  <ul>
  <li>Adjusting the volume of a classical mix changes the accoustics of the hall; all sustaining noise from e.g. the audience is louder as well as the reverb it creates.</li>
  <li>Adjusting the volume of a classical mix/master is almost always an excuse for having too much headroom on your recording and will result in dynamic detail getting lost. Therefore, always record in 24 bits if you decide to increase it.</li>
  <li>As mentioned: dynamic range in classical music is a piece of the music itself, even between the different pieces. Getting rid of it is destroying part of the musical contents.</li>
  <li>As a rule of thumb: never touch the volume of a part of a classical recording if the difference in dynamics is so bad that you can't listen to the recording in the living room without touching the volume button.</li>
