If you want to record a vocal or guitar, see the section 'How to record audio?'. This section discusses what to do with pre-recorded audio and how to use it in FL Studio.
There are many ways to add audio tracks or wav files to your songs, you can drag .wav, .mp3, .FLAC & .ogg files from the FL Studio Browser or a Windows file browser and:
- Drop the audio file on the Playlist - this will result in an Audio Clip pattern being created and sampler channel added. The Playlist triggers when and there the audio plays. You can also slice the sample up, delete some parts and move others around, to have only the relevant parts play. FL Studio Fruity edition will need to use the next method as the Clip Tracks are not available to you.
- Drop the audio file onto a Sampler Channel. This method is great to trigger the sample from the Step sequencer or a Piano roll. It is particularly useful with short percussion sounds or 'hits'. You can place pattern blocks in the lower Playlist and trigger song-length audio that way. The downside is you can't start the song in the middle while editing and hear the audio. You must start the song from the trigger point to hear it.
- Drop the audio file into Fruity Slicer or Slicex - and slicer will autoslice the file for you and lay it out in pianoroll. Depending on source material you may need to make some adjustments to the slice points and number (see the manual). For percussion and non-sustaining material - check out the unique "Fill Gaps" function which can do wonders for time stretching/compressing - you'll be amazed by results.
- Drop the file into Fruity Granulizer instead of Sampler. It can do a number of cool things: Granulizer can play your file from the middle when you change song position, it can also perform Acid-style stretching (see the "Fit" LED in SMP tab).
A word of caution - think about what you are stretching - depending on type of material - some things (drums, bass, non-sustaining riffs) belong in Slicer and can benefit tremendously from the "Fill Gaps" tool. Some materials can be stretched beautifully with Granulizer and it's "Fit" option - sustaining pads, strings, vocals - however play with other knobs on Granulizer for best results - some tuning may really increase quality of the stretch.
In summary - everything needed for what you want is already there. If you are an advanced user - you will quickly discover it for yourself.
