Selling Beats Online: MP3 Previews, WAV Masters, and Delivery Specs

Every serious beat store runs on a two-tier system, whether the seller planned it or not. Tier one is the preview: the tagged MP3 that streams on your BeatStars or Airbit page, the version with the producer tag every eight bars, the file casual browsers and would-be thieves get. Tier two is the delivery: the untagged files a paying customer downloads the second the payment clears — MP3 for basic licenses, WAV masters and often stems for premium and exclusive ones. Sellers who treat these tiers deliberately load faster, get stolen from less, and field fewer refund emails. Here is the whole workflow.

The preview tier: built to stream, tagged to survive

The preview file has exactly two jobs: start playing instantly when a browsing artist clicks it, and be useless to anyone who wants a free beat. Those jobs define its spec.

Tags are the security model

A vocal producer tag repeated through the track is the only theft protection that actually works, because it travels with the audio. Bake the tag into the preview bounce itself; never rely on the platform's player to overlay it, and never post an untagged version anywhere public, including a "quick preview" on social media.

Bitrate: instant beats immaculate

The preview streams over whatever connection the customer has, often mobile. A 320 kbps preview buffers noticeably on weak connections and delivers quality nobody needs from a tagged audition copy; a 96 kbps preview sounds cheap in a way that reflects on the beat. The working consensus lands in between: bounce previews at 128 kbps — a 128 kbps conversion of your tagged bounce streams essentially instantly and still presents the low end honestly. If your beats lean on airy hi-hat detail, run an A/B against a compressed 160-192 kbps version and pick the smallest file you cannot hear the flaws in. The bitrate FAQ explains what those numbers actually control, and the compression settings FAQ covers the tooling side.

The delivery tier: what each license actually ships

License names vary by store, but the delivery ladder is near-universal:

• Basic / MP3 lease: an untagged, high-quality MP3 — this should be a 320 kbps encode from your master bounce, not the preview file with the tag muted. Artists record over this file; give them the clean version.
• Premium / WAV lease: the untagged 24-bit WAV master. This is the file serious artists mix against, and its presence in the tier is why the tier costs more.
• Exclusive / stems: WAV master plus individual track stems, zipped. Stems are bounced from the session; nothing on this tier should ever pass through a lossy encoder.

The rule underneath the ladder: every delivery file descends from the lossless bounce, and lossy conversion happens once, at the end, per file. An MP3 lease made by converting another MP3 stacks two generations of encoding loss into a product someone paid for.

The export workflow, start to finish

From one finished beat, you need four artifacts. The efficient order:

• Bounce two masters from the session: the clean 24-bit WAV, and a tagged WAV with the producer tag printed in. Same limiter settings, same length, roughly -1 dBTP of headroom so the MP3 encodes cleanly.
• Make the lease MP3 from the clean master with a WAV to MP3 conversion at 320 kbps.
• Make the preview MP3 from the tagged master at 128 kbps.
• Zip the stems (exclusive tier) straight from the session bounce folder.

Name everything by beat, BPM, and key — midnight-run_142bpm_fmin_master.wav, midnight-run_142bpm_fmin_tagged128.mp3 — because customers reference beats by exactly those attributes, and because you will re-deliver files months later when an artist loses them. Store the whole set per beat in one folder; upload the preview to the store, attach the clean files to the license tiers, archive everything twice.

Details that separate professional stores

• Loudness-match your previews. A browsing artist clicks through ten beats in a minute; if yours plays 6 dB quieter than the last producer's, it reads as worse, not quieter. Run preview bounces through normalization to a consistent loudness so the catalog auditions evenly.
• Check tags on every re-bounce. The classic catastrophic mistake in this business is uploading the untagged master as the preview. Make the tagged file's name unmistakable and check it in the store player after every upload.
• Keep ID3 metadata working for you. Preview MP3s travel — embed producer name and contact in the tags so a file forwarded between artists still leads back to your store. The ID3 FAQ covers what fields exist.
• Answer the delivery-size question up front. A three-minute beat is roughly 7 MB at 320 kbps and 30+ MB as 24-bit WAV; stems multiply that by the track count. State it on the license page and refund emails drop.

The economics of getting this right

None of this workflow makes a beat better, and all of it makes a beat sell better — which is why established producers treat the export routine as seriously as the mix itself. Fast-loading previews keep browsers on the page through more of the catalog. Consistent loudness keeps your best beat from auditioning worst. Clean, instantly delivered masters generate the five-star reviews that platforms surface. And baked-in tags mean the leaked copy of your beat circulating on a mixtape site is a functioning advertisement with your name in it every eight bars. Two tiers, one lossless source, conversions done once, every file named so a customer email from six months ago can be answered in thirty seconds — that is the entire system, and it scales from your first upload to a thousand-beat catalog without changing shape.
