Render Song to Audio File

Rendering Song to Audio File

To create a WAV or MP3 file out of your song, you have to bounce it. This process is called "rendering" in Renoise. Rendering a song does not only allow you to sample the whole song but you can also render and save parts of it to for example reuse it as a sample file in other songs or other applications. By rendering each track from the song separately into its own file you can even post process your song in other multi audio track editors.

Rendering is only enabled in the registered version of Renoise. Its not available in the demo versions. Renoise will also not directly render a MP3 file, but will always save uncompressed WAV files. Those WAV files can then be easily converted to MP3 files with an external application.

Opening Render Dialog

You can open the render dialog by either hitting the "Render" button in the Disk Browser with the "song" category selected, or by using the global menu option: "File" -> "Render Song To Disk...".

To quickly render, resample and reuse parts of the song in the pattern editor, see Render & Resample Parts of the Song.

Part to Render

Specifies which part of the song (if you don't want to bounce the whole song) you want to render. Please note that muted tracks and columns are never rendered by Renoise. This way you can easily exclude tracks you don't want to export. Other ways to exclude parts of the song are:

• Entire song: Renders the complete song
• Selection in Sequence: Renders only the patterns from a specific sequence range. You can also quickly specify a range in the Pattern Sequencer and then open the render dialog from there with the Pattern Sequencers context menu.
• Selection in Pattern: Renders only the selected area in the pattern

Destination

Hitting the browse button will promt you for a folder where you want to save the rendered files to. Enter the name of the file in the ext field next to the browse button. The destination files will always be .wav files.

Render Options

• Interpolation: Select the resampling interpolation quality that should be used. "Cubic" is what was've heard when playing back and composing the song, "Arguru's Sinc" is a very precise interpolation mode that can not be used in real-time. This interpolation mode results into the best possible sample playback quality. Please see #Interpolation for more details
• Sample Rate - Select the sample-rate for the rendering. By default the currently active sample rate is selected, which is also recommended. Many DSPs may sound slightly different at different rates which might not be expected. If you change the rate to something else, then please double check the rendered result to see if this is how you want that it sounds.
• Bit Depth - Set the bit depth of the resulting WAV file. Renoise internally renders in 32 float bit, so you should use this format when you plan to reuse
• Save each track into a separate file - What it actually says if you want to have your recording mixed down in a studio, use this option. Sound-engineers like it better when they have all tracks delivered separately.
• Save each pattern into a separate file - Creates a wave-file for each pattern in the total sequence.
• Priority - Set rendering priority to Real (VST Compatability mode), low (render in background), high (as fast as possible). When setting the priority, consider the type of instruments and effects you use. If you use VSTI synths or VST effects, you are better off using Real mode rather than fast. Low will not guarantee proper rendering of VSTI / vst effect rendering. Real mode takes care the song is rendered according to the actual playrate and Renoise awaits the plugins to complete their cycles before going any further to render the next row. When using internal samples (RNI) and DSP effects only, the other two modes will suffice for good rendering.

(*)When you select to sample to disk up to pattern 04, it will only include up to pattern 03.

(**)Beware when using organic or bad shaped samples. They may have a perfect effect during play in the editor, when you use Arguru's sinc interpolation, the sample may sound very different from the generated wave-file than it does in Renoise! Listen to the two examples.Cubic rendered vs. > Arguru rendered

Notice the different sounds between the two mp3-files. Though they use the exact same sample and the exact same bitrate and frequency, the interpolation changes the sample-structure drasticly enough to create these differences. So try cubic interpolation first as well as the current frequency rate your sound-card is currently set to, to play your samples in Renoise before you do any bug-report about this.

Also, some settings may affect proper play of VST instruments, e.g. instruments are sampled at 44Khz, but you render in 96Khz and those samples suddenly play at 1.5 times it's original pitch.
