How to save a mixdown and export tracks in Reaper


Recording multiple tracks has been made very accessible and inexpensive by the likes of DAW (Digital Audio Workstation) software such as Reaper. Once you have recorded and mixed all your tracks, you will very likely want to turn those multiple tracks into a single stereo mixdown file.

To save a mixdown in Reaper, go to File->Render. Select “Master mix” in the “Source:” dropdown list. Select a directory and filename for your mixdown file. Select the output format such as WAV or MP3. Click “Render 1 file”, and a single stereo mixdown file will be saved in your chosen format.

Saving a mixdown file that can be played on any computer, phone or mp3 player is very easy in Reaper. There are however many options you can specify, and many ways to export parts of your song or individual tracks. Read on for details of exporting your mixes and individual tracks in Reaper.

How to save a mixdown in Reaper

Here is the easiest way to save a mixdown in Reaper, for those who aren’t bothered with the details…

  1. Go to File->Render…, or press Ctrl+Alt+R; the “Render to File” dialog will launch.
  2. Select “Master mix” in the “Source:” dropdown list
  3. Select a directory to output your mixdown file into
  4. Specify a name for your mixdown file
  5. Select the sample rate and number of channels – if you are unsure leave these at the defaults
  6. Select the Format: for your file from the dropdown list, such as WAV or MP3
  7. Click the “Render 1 file” button

This is typically what you would do when you have finished mixing your song, and want a file you can play on other systems, burn to a CD, share with someone else, etc.

By the way, one essential piece of equipment to use with Reaper or any other DAW is a good audio interface. I have been using Focusrite Scarlett interfaces for years, and they have always given me great sounding recordings for not very much money. You can buy the Focusrite Solo from Amazon (affiliate link) for a very reasonable price.

Reaper’s mixdown and render to file options

Even if you only did the above and accepted most of the defaults, you’d have a mixdown file ready to go. However, there are so many options for rendering to file in Reaper we’ve only just scratched the surface so far.

Here are explanations of the more commonly used render-to-file options in Reaper…

Bounds – select just part of your song to mixdown

You don’t have to export the whole length of your song. If you want you could export just the 1st 30 seconds, or the last 30 seconds, or the middle 2 minutes…you get the idea.

Why would you want to do that? Well, you could be wanting to send the intro to a writing partner to get their opinion on it. Or maybe you just want to hear the guitar solo section in the middle on some other audio systems such as a car stereo or a kitchen Bluetooth speaker. I’m sure you can think of some uses applicable to you.

The “Bounds” list in the “Render to File” dialog has the following options…

  • Custom time range : select this option and the “Time bounds” settings just underneath will become enabled. These let you specify exact start and end time stamps for your mixdown in minutes, seconds and milliseconds. e.g. you could export a section of 53s length from 1:20:00 to 2:13:00.
  • Entire project : does what you would expect; renders the entire length of your song from beginning to end
  • Time selection : this one renders the section between the time selectors in Reaper’s track view. Time selectors are those lines you can set by shift-clicking or dragging, and the grey selected area between them is what will get rendered to file.
  • Project regions : regions are a feature of Reaper where you can mark a section of your song e.g. verse 1, chorus 2, bridge, etc. This option will render all the regions in your project.
  • Selected regions : this option only outputs the regions you have selected. You can select regions by clicking the Region Matrix button, and clicking on the relevant Master Mix square at the top of the grid for the regions you want to include.

Source – saving a file for each track

So far, we have only really considered selecting exporting one stereo mixdown file. But Reaper is much more flexible than that. You can output one file from each track, only output selected tracks, only output selected media items, etc.

The “Source:” dropdown list in the Render to file dialog is the setting to use to specify the file(s) to export from which tracks.

Here are some of the more commonly used options…

  • Master mix : we have already discussed this one. It exports a single stereo mixdown file from the master track. It will export a file that sounds exactly like when you play your song in Reaper. So if you have any tracks muted for example, you will not hear them in the mixdown file.
  • Selected tracks (stems) : For every file you have selected in the tracks view, separate file will be saved for each one of those tracks. For example, if you have 5 tracks selected, 5 files will be output. These will include any insert effects you have on those tracks, but not send effects. You can export just one individual track from Reaper using this option.
  • Master mix + stems : A combination of the above two options.
  • Selected tracks via master : Like selected tracks (stems), but this option will include any send effects on the tracks.
  • Region render matrix : If you have any regions set up in your project, you can click the “Region Matrix…” button and select which regions on which tracks you want to export.
  • Selected media items : Each track’s content is made up of “media items”. You can select which of these you want to render – you don’t have to have the whole track. This option will export with insert effects included, but not send effects.
  • Selected media items via master : Like the above option, but will output with send effects.

These are not all the “Source:” options, but the ones you are most likely to need.

Most of the time, you will be saving a single stereo mixdown file (the “Master mix” option).

Before you export your mix to a file, hearing your mix through a quality pair of headphones or studio monitor speakers is essential. I highly recommend the AKG K-702 Reference Headphones (affiliate link), which you can get at Amazon for a very reasonable price. These are the headphones that I have been mixing on for years, with great results.

From time to time, perhaps you are looking to produce a set of files, one per track, to give to someone else to work on. You could use “Selected tracks (stems)” for this, which is one way you can export multitracks from Reaper. But there is actually a better way – see the later section on “Consolidate/Export tracks…“.

Output and output format options

I have lumped together the Render to File dialog’s “Output” and “Output Format” sections. This is because they are very closely related. There are also a lot of options here, and I didn’t want to just reproduce the User Guide in this article, so I will only cover the most useful and commonly used options here.

  • Sample rate: The sample rate of your output file(s). 44100 Hz (44.1kHz) and 48000Hz (48kHz) are the most commonly chosen options.
  • Channels: Most of the time you will choose stereo here.
  • Format: The format for your output file, such as WAV, AIFF, FLAC, MP3, Ogg Vorbis, etc.

The available options in the Output Format section change dependent on which output format you have chosen. I’ll talk through the options of the two most commonly used output formats – WAV and MP3…

Exporting to WAV from Reaper

The main option of concern here is the WAV bit depth. You would usually choose either 16 bit PCM or 24 bit PCM. If you are intending to burn your song to a CD then 16 bit PCM bit depth and a 44.1kHz sample rate should be used. For DVD audio, use 24 bit PCM bit depth with a 48kHz sample rate.

WAV format would typically be used when you want to retain the highest possible quality. With WAV, no audio information is lost because it is a lossless format, unlike something like mp3. WAV would be ideal for sending your mix to be mastered, for example.

Exporting to MP3 from Reaper

Export to mp3 from Reaper by selecting the MP3 (encoder by LAME project) option in the output format tab in the “Render to File” dialog.

When saving your reaper file as an mp3, the options are concerned with output quality. When mp3s first started to be used, hard disks were a lot smaller and internet speeds a lot slower than they are today, so it was acceptable to use low-quality settings to keep file sizes small.

These days, hard disks are enormous and internet speeds are much faster. Therefore, there is no need to keep the file sizes small – even the highest quality mp3 will still be about 5 times smaller than the equivalent WAV file.

Because mp3 is a lossy format, it is important to choose high-quality settings for the best possible sound. I would choose Constant bitrate mode with a bit rate of 320kbps, and would go no lower than q=2 (the recommended setting) for decent audio quality in the exported mp3 file.

Note that since the Render to File dialog has Primary and Secondary output format tabs, you can actually select two formats to output to at the same time. This way, you could output a WAV and an MP3 file with 1 click of the Render button.

If you are exporting mp3 from Reaper, you may be interested in how to do the reverse operation. Make sure to check out my article on how to import an mp3 into Reaper if you think you might want to do this.

Export tracks from Reaper for someone else to work on

I mentioned earlier that if you wanted to export all your tracks to individual files (i.e. one file per track) for someone else to work with, there was a better way than using the “Selected tracks (stems)” option on the Render to File dialog.

The best way of doing this, especially if they are using a different DAW to you, is to use the Consolidate/Export tracks… feature.

Consolidate/Export tracks in Reaper

Go to “File->Consolidate/Export tracks…”

This is a better method than the “Selected tracks (stems)” option, as consolidation is automatically done for you. This means making sure all the tracks start at the start of the project, and everything will sound at the right time in relation to each other when imported into another DAW.

This is vital to get right when giving your tracks to someone else to work with. For more details on consolidation and why it is so important, I wrote an article on what it means to consolidate a track. I highly recommend reading it if you are going to be sharing your tracks with anyone else.

You can see a lot of the options are similar to the Render to File dialog options…selecting which part of your project to export, which tracks to export, file format, bit depth, etc.

In the output section at the bottom of the dialog, you can choose to bring the consolidated files into your current project, or to save a new project with the consolidated tracks in it.

You will end up with a set of files that you can give to a work partner, for them to import into their DAW. They will then be able to work on the song in their just like you have been in Reaper.

Note that the files exported will not have any effects or virtual instruments on them. If you wanted the exported files to include your effects and instruments, you could first Freeze or Render your tracks. Select those tracks to consolidate/export, and you will have a set of files that sound exactly like they do in your Reaper project.

While we’re on the subject of virtual instruments, you will probably be interested in what, if any, virtual instruments or similar plugins Reaper comes with. If that’s the case, check out these two articles for more information…

Here are a few tips to bear in mind when giving your tracks to someone else to work with…

  • Number your tracks – give them names such as “01 – Drums”, “02 – Bass”, “03 – Rhy Gtr 1”, “04 – Rhy Gtr 2”, etc. This means that when imported into another DAW, they will appear in the order of the numbers, rather than any random order that the user will have to sort manually.
  • Name tracks what they are – give another user a chance of understanding what the track is. For example, call a track “Ld Gtr 1” rather than “Tony Sat Morning solo”.
  • Group like tracks together – helps with organization and finding things quickly. I like to start with Drum tracks first, then bass, then harmony instruments such as guitars and keyboards, then vocals. The order doesn’t really matter, as long as it’s logical and you keep it consistent.

Exporting the project for another Reaper user

Finally, there is an easy way to export your whole project (project file, tracks, media files) if you want to share it with another Reaper user…

  • Go to File->Save Project As…
  • Check the “Copy all media into project directory” checkbox
  • Choose a folder to save to, along with a project filename
  • Click “Save”

This will save everything needed to open that project in Reaper on another computer, including all the recorded audio, midi and media files. Give that folder to another Reaper user, and they can load in the project file and retain all your audio and midi tracks, your plugins and their settings, project settings etc.

You could even create a “.zip” file from the folder to email or share the project with them.

One thing to be aware of, is that the other user would have to have the same plugins installed on their computer as you have used in your project. Otherwise, tracks that use plugins that they do not have will obviously not be there on the track in the other user’s project. You can get round this by rendering tracks first, depending on exactly how you want to work together.

Conclusion

Exporting a mixdown or individual tracks in Reaper is very easy, and can be done in multiple different ways. Reaper also provides flexible ways of exporting your project and/or its contents. This enables multiple people to work on your song, whether they are using Reaper or another DAW entirely.
