Stemly Convert costs about as much as a coffee, and it does something many bigger tools don&rsquo;t: it converts a whole tree of folders and keeps every subfolder and every name. It works on Mac, iPad and iPhone, and it&rsquo;s not just for musicians.<\/p>\n<\/section>\n<div class=\"gm-content\">\n<div class=\"gm-section\">\n  <h2><span class=\"gm-num\">1<\/span> The problem every band with backing tracks knows<\/h2>\n<p>Backing tracks pile up: some are MP3s from a friend, some are exports from different sessions, some are 44.1 kHz and some are 48 kHz. The player itself tells you what to do. In my Stemly manual the golden rule is: <strong>convert all files to WAV 48 kHz before soundcheck<\/strong>. MP3s played as they are get decoded in real time on the processor, which is a risk with many tracks, and a WAV at the wrong sample rate can even play slightly faster. Converting one file at a time is tedious, and doing it by hand across hundreds of songs is how you end up with a mess of folders.<\/p>\n<\/div>\n<div class=\"gm-section\">\n  <h2><span class=\"gm-num\">2<\/span> The big plus: your folder structure stays exactly as it is<\/h2>\n<p>This is why I built Stemly Convert. You drag in a <strong>whole folder tree<\/strong>, choose the output format, and the app converts everything while <strong>keeping every subfolder, every name and the whole organisation<\/strong>. Same tree, new format. No sorting afterwards, no files lost in the wrong place.<\/p>\n  <div style=\"display:flex;gap:14px;flex-wrap:wrap;max-width:640px;margin:18px auto;\"><div style=\"flex:1;min-width:250px;background:#0d0d0d;border:1px solid #1c1c1e;border-radius:12px;padding:16px 18px;\"><div style=\"font-size:0.7rem;letter-spacing:1px;color:#8f8f94;margin-bottom:10px;\">BEFORE<\/div><div style=\"font-family:ui-monospace,Menlo,monospace;font-size:0.85rem;color:#e5e7eb;padding:2px 0 2px 0px;\">&#128193; Backing tracks<\/div><div style=\"font-family:ui-monospace,Menlo,monospace;font-size:0.85rem;color:#e5e7eb;padding:2px 0 2px 18px;\">&#128193; Song A<\/div><div style=\"font-family:ui-monospace,Menlo,monospace;font-size:0.85rem;color:#fbbf24;padding:2px 0 2px 36px;\">&#9835; Click.mp3<\/div><div style=\"font-family:ui-monospace,Menlo,monospace;font-size:0.85rem;color:#fbbf24;padding:2px 0 2px 36px;\">&#9835; Drums.mp3<\/div><div style=\"font-family:ui-monospace,Menlo,monospace;font-size:0.85rem;color:#fbbf24;padding:2px 0 2px 36px;\">&#9835; Guitars_L.mp3<\/div><div style=\"font-family:ui-monospace,Menlo,monospace;font-size:0.85rem;color:#fbbf24;padding:2px 0 2px 36px;\">&#9835; Guitars_R.mp3<\/div><div style=\"font-family:ui-monospace,Menlo,monospace;font-size:0.85rem;color:#fbbf24;padding:2px 0 2px 36px;\">&#9835; Vocals_Lead.mp3<\/div><div style=\"font-family:ui-monospace,Menlo,monospace;font-size:0.85rem;color:#fbbf24;padding:2px 0 2px 36px;\">&#9835; Vocals_Backing.mp3<\/div><div style=\"font-family:ui-monospace,Menlo,monospace;font-size:0.85rem;color:#e5e7eb;padding:2px 0 2px 18px;\">&#128193; Song B<\/div><div style=\"font-family:ui-monospace,Menlo,monospace;font-size:0.85rem;color:#e5e7eb;padding:2px 0 2px 36px;\">&hellip;<\/div><\/div><div style=\"flex:1;min-width:250px;background:#0d0d0d;border:1px solid #1c1c1e;border-radius:12px;padding:16px 18px;\"><div style=\"font-size:0.7rem;letter-spacing:1px;color:#8f8f94;margin-bottom:10px;\">AFTER<\/div><div style=\"font-family:ui-monospace,Menlo,monospace;font-size:0.85rem;color:#e5e7eb;padding:2px 0 2px 0px;\">&#128193; Backing tracks<\/div><div style=\"font-family:ui-monospace,Menlo,monospace;font-size:0.85rem;color:#e5e7eb;padding:2px 0 2px 18px;\">&#128193; Song A<\/div><div style=\"font-family:ui-monospace,Menlo,monospace;font-size:0.85rem;color:#4ade80;padding:2px 0 2px 36px;\">&#9835; Click.wav<\/div><div style=\"font-family:ui-monospace,Menlo,monospace;font-size:0.85rem;color:#4ade80;padding:2px 0 2px 36px;\">&#9835; Drums.wav<\/div><div style=\"font-family:ui-monospace,Menlo,monospace;font-size:0.85rem;color:#4ade80;padding:2px 0 2px 36px;\">&#9835; Guitars_L.wav<\/div><div style=\"font-family:ui-monospace,Menlo,monospace;font-size:0.85rem;color:#4ade80;padding:2px 0 2px 36px;\">&#9835; Guitars_R.wav<\/div><div style=\"font-family:ui-monospace,Menlo,monospace;font-size:0.85rem;color:#4ade80;padding:2px 0 2px 36px;\">&#9835; Vocals_Lead.wav<\/div><div style=\"font-family:ui-monospace,Menlo,monospace;font-size:0.85rem;color:#4ade80;padding:2px 0 2px 36px;\">&#9835; Vocals_Backing.wav<\/div><div style=\"font-family:ui-monospace,Menlo,monospace;font-size:0.85rem;color:#e5e7eb;padding:2px 0 2px 18px;\">&#128193; Song B<\/div><div style=\"font-family:ui-monospace,Menlo,monospace;font-size:0.85rem;color:#e5e7eb;padding:2px 0 2px 36px;\">&hellip;<\/div><\/div><\/div><p style=\"font-size:0.8rem;text-align:center;\">An example of a folder tree: the structure stays the same, only the format changes.<\/p>\n<\/div>\n<div class=\"gm-section\">\n  <h2><span class=\"gm-num\">3<\/span> How it works, in three moves<\/h2>\n<ol style=\"color:#8f8f94;line-height:1.9;font-size:0.95rem;\">\n    <li><strong>Add<\/strong> a folder (or files).
