Streaming apps love to advertise numbers like 96, 160 and 320kbps. But what do these numbers mean, and do they make a difference to what you actually hear? Here is a plain-English explanation.
What is bitrate?
Bitrate is the amount of data used to store or stream one second of audio, measured in kilobits per second (kbps). More data generally means the encoder can keep more detail from the original recording. A 320kbps stream uses roughly twice the data of a 160kbps stream and about 2.5 times the data of a 128kbps stream.
Lossy vs lossless audio
Almost all streaming at 320kbps or below uses lossy compression — formats such as MP3, AAC and Ogg Vorbis. These formats remove sounds that human hearing is least likely to notice, which makes files much smaller.
Lossless formats like FLAC and ALAC keep every bit of the original recording. CD-quality lossless audio runs at about 1,411kbps — more than four times the data of a 320kbps stream.
Common bitrates compared
| Bitrate | Typical use | What to expect |
|---|---|---|
| 96kbps | Data-saver modes | Noticeably thin and “swirly” on good headphones |
| 128kbps | Older downloads, basic streams | Fine on phone speakers; cymbals and reverb can sound smeared |
| 160kbps | Many free streaming tiers | Good for casual listening |
| 320kbps | Top lossy quality (Jammify’s maximum) | Very hard to tell from CD for most people on most equipment |
| ~1,411kbps | CD-quality lossless | Bit-perfect copy of a CD |
Can you hear the difference?
Between 96kbps and 320kbps, most people can — especially on decent headphones or in a car. The improvements show up as clearer vocals, crisper hi-hats and cymbals, more natural reverb and tighter bass.
Between a well-encoded 320kbps stream and lossless, the difference is much smaller. In blind tests many listeners cannot reliably tell them apart, particularly over Bluetooth, which re-compresses audio anyway.
Does 320kbps use more mobile data?
Yes. As a rough guide, one hour of music uses about:
- ~70 MB at 160kbps
- ~145 MB at 320kbps
On Wi-Fi this rarely matters. On a limited mobile plan, you may want to listen at high quality mainly on Wi-Fi.
How to get the most out of 320kbps
- Use wired or good Bluetooth headphones. Cheap earbuds hide most of the detail.
- Turn off “loudness” or heavy EQ presets that exaggerate bass and treble.
- Use a stable connection so the app does not drop to a lower quality to avoid buffering.
The bottom line
320kbps is the sweet spot for streaming: it sounds excellent on nearly all equipment while keeping data use reasonable. That is why Jammify streams at up to 320kbps for everyone, free. Hear it for yourself, or see how Jammify compares in our Jammify vs Spotify Free guide.
