ReplayGain your music using mp3gain

ReplayGain is the name of a technique invented to achieve the same perceived playback loudness of audio files. Read more on Hydrogenaudio.

Set all files to 92db – this is the most used loudness now-a-days (it’s recommended also in Serato DJ software and most streaming platforms seems to use same value). You might want to use 89db if you are listening on a Hi-Fi system – in this case just ignore the -d 3 option.

The suggested loudness is ~89, so we add 3.

mp3gain -d 3 -c -p -r *.mp3


mp3gain -s r -d 3 -c -p -r *.mp3

-s r this will ignore the replaygain information already stored in the file

-c will ignore clipping warning, use -k to lower the gain to not clip

-p preserve original timestamp of files

-r gain per track (as opposed to per album), it’s good for collections, best of, etc.

recursively apply gain to all your mp3 files

  • it works also for file names with spaces 🙂
find . -iname '*.mp3' -print0 | xargs -0 mp3gain -d 3 -c -p -r


Plain Text Messages in Apple Mail

I am a fan of plain text, so I prefer using plain text mails whenever possible. Here is how you do it for Apple Mail ( OS X El Capitan, but probably works on most versions).

Change the (default) format  for all messages:

  • go to Mail > Preferences, click Composing, then choose Plain Text as Message Format.

Change format of the current message:

  • go to Format > Make Rich Text > Make Plain Text

Reply to messages in the same format you received them:

  • go to Mail > Preferences, click Composing, then select Use the same message format as the original message

Most probably you will also want to use fixed-width font for plain text messages. So, go to Mail > Preferences > Fonts & Colors and choose Use fixed-width font for plain text messages
