Concentrate FIRST on making a good mix. By way of example, analogue tape can capture a dynamic range of anywhere between 50 and 70 dB (with 70dB rarely achievable even on the best systems). weblink

Only frequency content with amplitudes above the masking threshold is then 'sent' for encoding. Obviously, this results in the output frequency content being slightly different from that of the input signal. This determines how small the size of the audio file is. The audio is stored digitally on a CD via a technique known as PCM, or Pulse Code Modulation. http://www.sevenforums.com/sound-audio/168984-how-decrease-audio-quality-without-losing-channels.html

from an audio CD) then you can either record without conversion (if you want to preserve maximum quality) or compress it (if you want to reduce the file size). High frequencies (4000 Hz plus) tend to sum to create an overly bright or 'brittle' sounding mix, so don't be afraid to cut them back. For example, try listening to a track at a high playback level, and then turn it down and listen again.

Spotify's standard free service uses the Ogg Vorbis format at 160kbps for computers and 96kbps for mobile devices, while their Premium subscription service can stream at 320kbps.

Audacity Download The bottom line is that higher bit rates produce better-sounding encoded files, and ultimately your ears must be the judge, based on the type of material you are encoding.

Frequency Content & Noise Addition Perceptual coding relies on our ears' inability to hear frequency content obscured by other frequency content. Mp3 Compressor The main principles used are described below. • Minimum Audition Threshold: The human ear is not equally sensitive to all frequencies.

Consider also, placing Fruity Limiter in the last FX bank of the master track. Scattered about this manual you will find other tips and techniques, particularly in the sections associated with Effects Plugins, keep an eye out for them. Mp3 Bitrate

Exploiting Psychoacoustics Psychoacoustics is the study of how humans perceive sound, and it's relevant here because advocates of lossy data compression argue that when listening to CD-quality audio, it is impossible seriously all it shows for me is "Stereo". Sampler Channels respond to the default Circular Panning Law. http://harryhooie.com/how-to/how-to-convert-zip-file-to-normal-file.html If you really need reverb, one good compromise is to automate the reverb amount, down in the busy parts, up during the solo when it's needed. ...and more.

And we haven't even discussed teenagers happily listening to bad audio through their built-in mobile-phone speakers, or 50p ear-buds. Simply put, lossy formats always exhibit some quality loss, because the audio content exiting the decoder on playback is not the same as the audio content that originally went in to Pay attention to the foreground (the loud, obvious claps) and the background (the details of the unfocused individual claps).
