I assume that you export sound in order to import it somewhere else. This process has a lot of details and used to be done in the step called "mastering" in the old recording days. I'm no expert, but I could try to give you some pointers.
Your first choice is whether to compress or not. The best known example of compressed formats is probably MP3. ...
Route the output of each track to another empty track. Record arm the destination tracks and then hit record. When the record pass is done all your effects and automation will be "printed" to the new tracks.
8-bit 8K isn't going to be great quality in any case, but WAV is as good as you can do. Straight uncompressed MS-format (RIFF) WAV is the most compatible format for interchange.
There are two senses of 'compressed' at work here. U (mu)-law and A-law refer to schemes for compressing dynamic range, not for reducing file size. Typically they would be 'expanded'...
Convert the m4a file into a 48kHz WAV file first, using iTunes, Audition, or QuickTime Pro. Import the wav file into AE, and position it in the same place as the video file. Make sure the loudspeaker icon is enabled on your new audio track.
Yes, there will be a difference. Mp3 is a lossy codec that deteriorates with every generation. It's bad practice to use mp3 (or lossy compression in general) at any stage where the audio may yet be edited or reencoded. Some programs are smart enough to simply copy the original audio stream without reencoding if possible, but I can't say whether this applies ...
WAV is a lossless raw format, so the short answer to your question is no.
The only way to reduce the filesize is to :
use a different export format, or
shorten the length of the project.
There are various lossless compression tools available to you such as WAVPack, FLAC.
The lossy compression tools that could be considered are aac or mp3.
After many headaches I finally found the answer: it has to do with a mismatch between global and export Sample Rate settings.
Here is how to fix the issue:
Go to Ableton Live's Preferences / Audio and note your Sample Rate : In/Out Sample Rate setting.
Now try exporting again and make sure that the export setting is set to the same Sample Rate as your ...
Based on Nuendo...
You should be able to do an Export -> Audio Mixdown which will allow you to select an output channel of a particular format (mono, stereo, whatever) to allow you to export the audio through that master channel. This is a fairly basic process in cubendo. "Saving" is normally done at a project level. You need to 'export audio mixdown' in ...
FluidSynth does this fairly simply. The user manual describes the large list of options available to tailor operation, but to render a MIDI file to WAV the simplest command is:
fluidsynth <soundfont file> -F <output file> <MIDI file>
fluidsynth "GT Steel.sf2" -F "high-hopes.wav" high-hopes.mid
Some alternatives ...
I'm fairly certain I know what the problem was now.
Figure will always export the current file, in whatever state it was last saved in. This means if you mute 2 of the 3 tracks and export, you will not get the resulting single track you expected. You have to mute the undesired tracks, then save, then export.
I had known this and thought I was saving, but ...
As far as I know there is no "direct" way to export a sample built from reason synths/samplers. What you can do is:
Set your reason project to only play the single note you want to export (clear the sequencer and only leave a single note) and use the "Export as WAV feature". Reproduce for each note.
The other way around is to use signal routing on your ...
